This Can Coat Anything in TITANIUM

- เผยแพร่เมื่อ 17 ต.ค. 2024
- Titanium is a pretty fantastic materiel on it's own, but if you can coat things in it you can radically alter their properties. Or just make them super colorful. In several previous videos we've explored how to coat all sorts of things in a variety of metals and materials, but titanium was one of the few that refused to work no matter what we tried. In this video we've finally cracked it and using thermal evaporation manage to coat all sorts of things in titanium metal.

I used to work on ultra-high vacuum systems in the range of 10^-12 Torr. The thermal evaporation process is just simply that the heated material is overcoming the vapor pressure in the vacuum. This works with damn near anything you can put in the chamber. For best results, you want to get the vacuum as high as you possibly can. Looks like you're intent on switching to a stainless steel vacuum chamber which is the first step, the next step is that you need to use as much refractory material inside the chamber as possible so no organic materials or aluminum! Problem with organics is that they off-gas and aluminum is porous so it soaks up junk in atmosphere that it will off-gas for all eternity inside ultra-high vacuum environments, both effectively poisoning your vacuum. Also, you'r going to want to keep everything completely spotless clean, like clean room clean. A fingerprint on the inside of the chamber will poison the vacuum. Now for your pump setup, if you can get your hands on one, a turbo-molecular pump paired with a roughing up will get you to -9 Torr if you have proper material and good procedure, just don't turn the turbo pump on in regular atmosphere or you will grenade it.
Can't you just brush it on with a fine stranded brush?
@@gangleweed No. I don't think you understand how incredibly thin these coatings are.
So an aluminium vacuum tank won't work?
@@johnnycash4034 depends on vacuum, 10-6 Torr is OK, 10-9 Torr - no way! Aluminum has very porous surface, it will outgas forever.
@@odissey2 thanks for the reply.
That makes sense. The seals I'm going to be using are KF flanges with rhe o-rings so not made for UHV anyways. So I geuss aluminum should be fine then? But yeah as you said with the porosity that might be an issue. Although if doing Al coating, then the inside of the chamber would be coated with aluminium in anyways.
You should see how coating spider silk changes its properties. I've wondered before what it would take to make a suit that looks like metal but acts like cloth or even silk.
It’d become brittle
Coat it in a flexible alloy or whatever
@@kanesmith8271 So gold would be great but wouldn't work. Nitinol?
@@Cheddar555 yes yes yes!
im stealing your suggestion
@@smartard Good luck with that😁
When you peel off the vinyl, it leaves behind some glue. If you try to wipe with IPA or acetone, it will into unwanted areas. I have etched thin metals using vinyl. In that case the acid reaction is quick. Perhaps you need to peel of the vinyl cuts off, before pasting it onto a clean sheet of glass.
Yeah that too, its works in lab

Pls try coating a playing card! That would be awesome
It would be a coating like as if he painted it(IF the card servived) sorry. Good idea tho
HÆX A. Painting something doesn’t produce these shiny interference patterns though
@@among-us-99999 "coating" "as if"
Also there's paints that can do simular effects as well as additional additives you can mix into the base even techniques used when painting and as it dry/sets
I think he might have meant with like a stencil of the cards template, so you'd have a shiny metal number, and shapes, or even the other way around.
Not sure if you realize how thin these oxide layers are, but it wouldn't be like a solid metal card.
I'm interested in materials science, can anyone tell me how to learn more?
This channel is incredible
Keep watching
Try checking your library, sometimes they might have old textbooks, or do what I am doing and go to college.
It is a multidisciplinary field. MIT opencourseware on TH-cam has lecture series for many engineering related fields. It'd be helpful if we knew what sort of knowledge level you are starting with.
Litterally start reading books. You dont need someone reading you lessons.
Learn how property's mix together to create something new, all it takes
I use titanium sublimation pumps for my vacuum chamber! The filaments for a TSP are mixed with molybdenum to increase their strength at high temperature. I have a lot of those, let me know if you're curious to try them.
"Local rock shop"
That a normal thing in other countries?
Capybara oh yea next town over from me has a rock shop lol
In Central USA
yeah most towns in the USA that i've visited/lived in have at least one gem/crystal/fossil shop
They are common in the Southwest USA .i cannot write from experience about other regions in the USA, or, other nations.
i'd imagine that they are common in Burma (Myanmar), Thailand, India, Afghanistan, Brazil, South Africa, Australia, and as well as many other mineral producing regions.
Where are you from?
@@pengu2250 Here is a list of rock shops in Germany.

I am certain that Denmark sells Amber
I will wager that if I search out these Gem and Mineral Supply Shops in Europe ten I will find hundreds of stores in Europe.
I will guarantee that you will not find something if you are not looking. are intentionally blind.
@@24kGoldenRocket I can confirm, common in brazil (or at least in my city)
I am SO glad I found this channel.
If anyone wants to discuss design improvements, maybe instead of a single filament, a filament cage of sorts would help to provide a more uniform coating and also slightly increase the resistance, so you don't fry the VariAC as easily
same i just subbed today ヽ(^。^)ノ
Soumya Khanna
i think it might be a plasma that fills the whole vacuum, but it does sound plausible that the side facing the coil would get a heavier coating. i don't know exactly why that would be, but it seems intuitive. so multiple coils surrounding it might help.
@@BothHands1 great! Watch the recent alcohol aging video too
@@BothHands1 sputtering is caused due to atoms literally shooting out of the coil at high temperatures, so yeah a cage would help in providing a more uniform coating
bought a e-copy of the book you recommended, it was delivered before you finished talking, this is an amazing world
Great find! I'm stealing your idea to evaporate titanium onto a leatherman.
goddamn shit this is the real samy kamkar ,where are the likes!!!!! your awesome man
The heat will destroy it's tempering?
You can use tungsten wire as a base wire. Tungsten melting point higher than titanium. Roll the titanium wire over tungsten wire for best result.
Samy! It’s Bradley =]
With 20 years in semiconductors we did this stuff for fun. If you use photo resist you can make a mask with a projector transparency sheet and a laser printer.
We used cyros with organic media for final gettering, it brings vacuums from -5’s to -8/9’s
Woah... that's a "real" experimental prototype: "I hate it... I hate using it... most of my material selection was garbage"!!!!
You glass jar has quite an "interesting" coating of materials after all these experiments... I would keep it as a souvenier rather than clean it up for future use.
Quite a few years ago I read a paper on 3D printed scaffolds that were made from plastic at a very fine scale and this plastic was easily dissolved in certain solvents. So what they did when they had this very very tiny scaffold is they coated it in metal and then dissolved away the plastic leaving a very tiny very fine hollow tubules in a scaffold form. You might have fun trying a project like that. Please let me know if you try this thank you very much for your videos. I always enjoy them.
When i was doing that at university, we suspended the material to be coated at the top of the vacuum chamber. We also used the "boat" design to heat our coating material. Lastly, we used a laser to measure the thickness of the coating (with interferometry) in real time. The chamber was about 1 feet high if I recall correctly.
Is you glass slide made out of SiO2? If so, could the O2 be reacting with the titanium to form TiO ? Hence the oxidation contamination could be from the glass itself?
@Michael Nilson i'm pretty sure there was the experiment with microwave plasma where he was using Borosilicate glass that had sodium ions in it. which messed up results too.
stuff like t his is always interesting.
the nice adhesive properties of titanium films onto both glass and pure silicon are because of surface reactions. It is absolutely plausible that a too thin titanium coating on glass fully oxidizes quickly, both from the glass and from the atmospheric side.
A different material often used for sputtering metallic layers on microchips is an alloy of tungsten and titanium.
Not quite, but actually maybe very much on the right track. Glass likes to have chemically bound water -- Si-OH groups on the surface. That might screw up bonding. Heating I think is the solution?
Interesting question. The Ti might have enough energy to reduce the surface of the glass. I doubt it will have the energy to bury itself all that deeply in the glass and once that interface is created the Ti wouldn't really be able to react further.
@Michael Nilson it was sodium in the glass causing issues. He used plastic instead.
literally just watched your video on magnetron sputtering like 5 minutes ago
I´d recommend putting some step-down transformer between the variac and filament. That way you get much more control over it and there´s no risk for the variac. The transformer from a lead acid battery charger may be a good option.
Also, THANK YOU for recommending this book in your last video. It really is an awesome book. Just a few days ago I also read about these getter pumps in there.
I don't know if it would even be possible but have you ever considered trying to sputter glass? If there was a way you could get it molten in a vacuum it might work. It would be cool if you could coat a bug in glass. Maybe as a way of preserving it? Maybe it's a dumb idea but if anyone has already done the research it would be interesting to know if if it's even possible.
it's pretty cool how a lot of high tech stuff is actually made of pretty low tech ideas but all combined in such a precise way that they produce very reliable and accurate responses as well as the miniaturization of them
you deserve more subs. quality content.
I am an electrical engineer but because of your video, I start loving material science.
This stuff always gets me excited to build again.
Man do I need another workbench.
Inspiring stuff as always!
I bought the book when you mentioned it in one of your other videos & it is AWESOME!
Ur channel is truly the best channel on YT. Love from Croatia.
I highly recommend avoiding vacuum grease at all costs. It's hell, gets everywhere, and kills your vacuum. It's outright banned in most labs for this very reason.
The only two proper ways to do vacuum feedthroughs are to either have glass-to-metal seals(out of reach for you to make, and probably over budget for something DIY), or, the cheap and easy way - to use existing viton o-rings for KF flanges, and to make a flange seal outside the vacuum chamber, with two flat surfaces squeezing the o-ring, while the thread(with slits cut in it!!!) only provides mechanical pinching force. Both real and virtual leaks will haunt you if you don't do it this way.
This also applies to the metal chamber you're building. Either just buying proper feedthroughs($$$) or building your own out of blank flange caps.
The endcaps of 'neon sign' tubing (low melting point leaded glass) are cheap and provide a way to get _wire through glass into vacuum_ that do not leak. Also, those electrodes are hollow and have getter inside them, which can be activated with a high-voltage discharge through imperfect vacuum. So use some just for that, and for general feedthroughs, cut them short on the hollow electrode side and take out the hollow electrode.
@@YodaWhat Almost correct, but they use borosilicate. Lead and soda glasses require gentle post-treatment with annealing, otherwise they're guaranteed to crack. However, there's no cheap off-the-shelf way to seal tubes of that diameter to chambers.
@@Spirit532 Having worked with a maker of Neon Signs, and closely observed his use of Propane and Oxygen-enriched Air to heat his glass, plus his evident lead poisoning, I will stick with my original statement. Working borosilicate glass requires much higher temperatures than his setup, typically Oxy-Acetylene flames. Then, the glass is annealed at the same time the electrode getter is activated, by passing much more than usual power through the tubes.
@@YodaWhat Borosilicate does not require an oxyacetylene flame. You can soften it enough to work it with an air-propane flame, or work with it properly with either oxypropane, or what I'm using to make glass to metal seals, air+MAPP(though I will switch to oxypropane, some of my operations are uncomfortable without the option to get a sooty carbon flame).
I've also used air-propane to make borosilicate pipettes in the past.
As for annealing - I have no experience with neon sign manufacturing, but I'm assuming that blasting the tube with a few hundred watts is just about enough to get it around the annealing point, but the stems come pre-annealed anyway, you're only annealing the joints and bends.
@@Spirit532 Ok, if you say so, but the makers of scientific glassware I have seen at work were using OxyAcetylene, which is more expensive and much hotter than any other common torch mixture. Anyway, here is a chart of various relevant temperatures for several types of glass: slideplayer.com/slide/4235773/14/images/18/Important+in+glass+forming+operations+are+the+viscosity-temperature+characteristics+of+glass..jpg
"...and that's only barely scratching the surface."
I see what you did there.
I see what you didnt do. Not made your own original comment.
As always... A great video.... I've never been interested in coating anything before now, let alone in Titanium...
Can you coat cast iron with stainless steel to protect the cast iron from corrosion and still get excellent heat retention?
I got super excited watching this!!
Just what I was looking for! pure magic ✨
Thanks a lot!
Hey dude, I love your videos. There is another way you can improve your build, instead of using titanium or aluminium wire, you can coil up tungsten wire, and run high current in it, it can easy get to very high temperatures, if you insert aluminium or titanium wire inside the coil it will vaporise the metal and coat everything you have inside the chamber. I've been using this method to coat surface mirrors, with a hacked MOT, and, Grant's scariac. Hope this info will help in a future build.
For the calcium evaporation in the ion trap, that i work on, i built an oven from a steel rod wrapped with tantalum wire and insulated with ceramic. Granted for trapping ions, only a few atoms of calcium are sufficient. Great video, keep up the good work.

It's stange how's the internet reacts on interesting things. This is an truly awesome video and got so few views, good narration, interesting theme, I'm glad that I've found this channel!
Absolute game changer. Building my own this winter
As a Vape Enthusiast, I know a bit about Ti heating coils; you should be using DC Voltage, with 5 V max. I'd consider making a "Clapton" type coil wire for this apparatus (multiple parallel internal cores - like a freeway, and then fuse them together with an outer wrapped "sheath").
Strangely, I always thought fellows like yourself were aware of Moore, Davis, Coplan/Building Scientific Apparatus. I am thrilled you were able to discover it. My well-loved copy graces a central place of honor on my bookshelf. Few texts I have ever come across are so profoundly complete.
Moore, et al., truly did write a fine text. I have a copy of the 4th Ed. on my shelf, and refer to it regularly.
I love your sense of humor. "It's terrible, but f it - it works" was basically the theme of my PhD thesis, so I can relate ;)
This is becoming my favourite channel, timeless science.
You are some sort of genius my friend.
PVD is a pretty neat technology. We use it a a lot in manufacturing, because it can add a TON of wear resistance with just a few microns added to the metal.
Does the coating harden the surface? my thought is on coating 3D prints like gears to make them more durable
so awesome i found your channel. i wanted to understand this whole rainbow anodizing process for so long.
First off, phenomenal video and congrats on yet another DIY conquest! Second, I can't decide if I'm more excited or furious that titanium sputter coating is as simple as "add heat" (minus the vacuuming steps ofcourse). Now, I may be but a lowly student of mechanical engineering, but as fellow vacuum/plasma/high voltage enthusiast I have some ideas that might improve the process. No idea if these will actually work, their just my best guesses after watching your video, but here goes.
1) Assuming that a straight titanium wire sputters titanium atoms in a similar pattern to how a fluorescent tube lamp in a tanning booth emits photons, if you arranged a bunch of these straight wires in an arc above the target such that they are parallel to the arc's axis of rotation (same configuration as the lamps in a tanning booth) it should concentrate more sputtered titanium on the target than a simple flat array of straight wires would. As well, by increasing the central angle of the arc it could help get titanium around tricky corners of the target. Or you could make it a full rap around cylinder of straight wires like a sort of cage to do a full 360 coat, but this might be a hassle to set up.
2) It might streamline things if you made the titanium wire preformed titanium wire elements. So taking my suggestion of the titanium tanning booth as an example, if you had the ends of the straight wire sections come together to form two bulkier wires (one per end) and then curled those bulkier wires in loops slightly larger than the bolts you used, so long as you are gentle with it all you have to do is put the target in position, take the top nut off of each bolt, drop in the preformed wire arrangement, replace the nuts, and then bam you're ready to start the process. This way, once you find the best wire arrangement for a given process you can just stockpile a bunch of copies of that array and swap in a new one as soon as you need it.
3) As you mentioned, this process is commonly used as a secondary vacuum pump, so maybe if you have a big enough chamber you could install a second heated titanium wire on separate set of bolts to act as a secondary vacuum pump. You could put it off in a corner somewhere so that it won't have much impact on the coating process and connect it to a separate circuit so that you can run it for a while before heating up the coating wire in order to improve the vacuum. My guess (and it's 100% a guess) is that while the geometry of the coating wire has the most effect on coat uniformity for a given target, the deeper vacuum may improve the repeatability of the results by further removing stray gas atoms from randomly intercepting the titanium atoms being sputtered from the coating wire.
Anyway, on the off chance that you do read this and that you had the patience to read through my likely bogus suggestions, thanks for all the help your videos have given in the fields of vacuum systems, plasmas, and high voltage circuitry. And as always, I'm looking forward to your next video, whatever it's about!
You have good suggestions there, but to coat evenly from all sides, it is perhaps simpler just to make a loop large enough to surround the target. Study of the ways filaments are supported in incandescent light bulbs can be instructive. Also, (and especially if desiring the beautiful golden hues of Titanium Nitride) use Nitrogen purge gas instead of Argon. It will also make a much better vacuum via _sputter pumping_ than Argon, because Argon will not combine chemically. Argon is an _inert gas._
Whoohoo, yay for bio season. I'm still fascinated by your mushroom workshop. Well I'm fascinated by everything you do. Do you plan to combine the spidersilk producing yeast (eventually) with komboocha? Spider silk strengthened scoby?
BEST phrase I think I've ever heard 'It works because... SCIENCE!' 👍
Fun with Ti wire. I use Grade 2 Ti wire in my vape- I make my own coils. I love Ti- I'm a mechanical engineer who designs/builds shell and tube heat exchangers (my work also has a machine shop) and we're constantly using Gr2 Ti tubes (and tubesheets) in retrofit and new build heat exchangers. We also do Ti explosive cladding to steel for tubesheets. I thought it was very cool to see your work here. Keep it up man! Subbed.
We got a rock shop, expensive tho. I have seen rainbow quartz and was curious how they make it, now I know. I love your channel, it always makes me realize that I want to do more and that I'm capable of it. I might start coating things in metal now. This makes me want to learn everything I don't know about electricity, and how to properly make vacuums.
Applied science noted in a video (maybe the SEM video(s)) seal selection in vacuum systems will off gass. You already noted this, but I'll corroborate your assumption that the buns seals, and especially the vinyl likely influenced the tests;if not all, then definitely the vinyl masked circuit on the slide.
Awesome video, I don't know how I'm just stumbling on this channel but I'm excited for all the new content to consume. Thanks for sharing!
Thank you for plugging sam zeloof
I have been wondering how to do this

Thank you very much.

300ms of ????? and then chuckle, best kind of joke, thanks.
So glad I’m subscribed. You’re playing with plasma like no big deal. Love it
Impressive stuff! Wish I was this inventive! Thanks for sharing.
The things you do and the way you explain them are fantastic! That being said, your connection of the copper leads to the nut was worrying. Haha. Awesome stuff! More than badass!
How well does the titanium coating stand up to wear and tear? If it stands up well it would be great to use it for strengthening things like copper and steel buckles or sword fittings or even firearm parts.
I doubt that the titanium coating is contributing that much mechanical strength to the objects it's coating. its purpose in these cases would be more aesthetic
I'd love to see aluminium and copper coating by evaporation :)
What a great idea. I've got a pair of titanium (so it claims) scissors, and I've abused them ruthlessly. They just don't rust. Even stainless steel would have rusted given what I've done to them. They cut well too. But honestly, they feel like steel, and I really wonder what the real composition of the allow is.
Lets not forget how amazing a simple zinc coating can be
I am so happy I found this channel front the shokugeki cooking video
00:36 Barely scratches the surface!
But you did a good job for such a shallow, surface level overview. You always know just the way to lay it down, gold!
You think a DC welder would work for this? I kind of want to buy a vacuum bell now, and see if I can make one that adapts to my MIG welder. Just attach the ground clamp to one probe, and make the other probe a wire with a small clamp on it to grab on to the contact tip to complete the circuit. Take the wire out for obvious reasons, then mess with the voltage to find a sweet spot. If you're burning coils too fast, make the over all wire longer. Make the span wider, and/or make the coils bigger. Maybe even double coil like a modern incandescent filament. You're also creating a magnetic field in a vacuum by using a coil of DC current. Try placing your object on one side of the coil to see if it's lofting the titanium in one direction.
Please try induction heating coating. I did a few yeas ago and it works as good as with the coil. Just use a tube instead of a coil, it's easier that way. Also, have you tried to make Molibdenum or berilium mirrors?
Try combining Ar and O2 to get a better control over the oxide layer. GL
Gonna have to pick up a copy of that book!
Could you do this without the argon and just the vacuum pump. Will the titanium still coat? Will it just be less efficient and need more tries versus with the argon?
If you plan on doing this often, I’d invest in a low-voltage constant-current driver circuit of some kind. Perhaps even one with resistance-measuring negative feedback, though that one would almost certainly need to be a home-brew circuit.
What if you give the rocks some heat? That colourful spot on the rock could be from proximity to the filament.
You can get cheap 3 terminal ceramic screw terminal blocks on AliEx. Loop your wire between 2 terminals and make a stand inside the container attached to the 3rd.
You've also got a repeatable alignment jig. How about magnetically coupling a couple of wire coils with an interference shield above them, and build it into the base? Then your only external connection would be the vacuum fitting. Why not build that into the base as well? Then you would have a passive container, and the flexibility to change it to suit your needs.
This is like finding a cool stick as a kid and doing everything you can think of with it
4:00 - You need to look up getters in vacuum tubes.
Since it's in a vacuum, could you coat something with lithium?
Getter coatings are also sometimes used in lightbulbs.
Damn this guy is a genius mad scientist!
9:39 did you say golden? Could it be nitrogen contamination ergo titanium nitride? If it is, that is a blessing, I've been trying to do other sputtering configurations, but this one seem cheaper and easier by a lot.
It is TiN. However, you're not going to get the things you probably want to get by coating things in TiN.
@@Spirit532 I mean would that thin of a coating not be enough for an implantable magnet? Not that I'd ever trust a magnet I coated myself but it's interesting
@@Enderbro3300 It would be! But the coating quality, uniformity, thickness, and chemical properties(oxide/nitride content) is pretty much impossible to control using this kind of hacky setup.
@@Spirit532 Yeah, i would not risk the coating quality in an implant. However i electroplate small pieces and this technique with some adjustments can expand my range to simple pvd like finish without the price of a full sputtering setup. Titanium (specially titanium nitride) cannot be electro plated unless you have sodium metatitanate available and you believe some old russian recipe.
0:30 - The light reflecting off the table and the light straight into the camera lens are different colors and shows off the dielectric property in a really cool fashion. I'm disappointed that the photographer didn't set the other three up in a similar way.
You are such an impressive person it is exhausting to watch your videos because I’d never have this endurance for details…
Very impressive and equally as interesting. Is there applications for corrosion resistance, such as hunting rifles or knives. I think you've really got something here, keep up the good work!!
Best channel in all of TH-cam.
Those rainbow effects in titanium are done in jewelry a lot through anodization. You may be able to start from the black layer and build up oxides through anodization to the desired level of refraction.
Can a dimmer be used instead of variac? I mean it's just a heater, right, it could be much simpler solution and no current limit? Have you tried in less vacuumy environment?
I'm getting really hyped for your neuron project, especially if it gives me ideas on how to make a computer using neurons which is definitely something I'd want to try at some point and should hopefully be theoretically possible.
Have you ever thought about adding bake out lamps? Best way to get the water adsorbed to thr surface of your chamber is heat. You can use lamps from an incondecent work light.
Why didn't you seal screws with teflon tape?
Hold up is noone gonna talk about how he subtly mentioned he might've synthesized diamond???
making small diamond crystals is easy. Making big ones is hard.
Not really "diamond" but "diamond-like", with all kinds of non-diamond stuff in it, including soot, graphite, graphene and carbon nanotubes of many types.
You can buy bags of PVD diamonds for just a few hundred dollars. It's a common material used in many places. Optical windows, abrasives, etc.
A tiny layer of diamond isn't really a big deal.
The price of Diamonds is artificially inflated by the DeBeers company.
3:37 getters were/are used in vacuum tube manufacture, the heater element already being an integral part of the device.
What about anodizing after you coat it with the Ti. Im sure you can get all the colors you want at that point.
I appreciate the “scratching the surface” pun at :38
damn dude ,you are way ahead because i never even heard or Ti coating or plating as common process ,,i played around with Cu,Ni,Ag etc in my electro plating setup and had a hard time coating Al but this is way advanced plasma type star trek style propulsion core tech lol
How durable is the titanium coating? Does it easily peel off?
Love your projects. I only have one issue with "WE" doing something. All I did was press the like button. 😂
You get the rainbow from titanium because of a thicker than normal oxide layer. In order to get any other color than grey/ black, you need to encourage the oxide layer to grow more than its natural couple nm. Straw starts around 20 nm. Blue starts around 40 nm Either heating the Ti in the presence of oxygen or using a chemical process to grow the layer is required.
i'ts the same process usded in vacuum tubes manufacturing. nice video
I have been looking for this process! Thank you!! What type of titanium is used to achieve that rainbow effect on crystals?
Aluminum coatings on the inside of lamps seems to be aluminum slug in a heating element, usually the same element that will be the lamp's filament. The videos on it seem to also use a metal shield to ' force ' the coating only on the back as the metal also gets an aluminum coating. You might want to try it withnyour current setup with a small rod of aluminum inside the titanium, just keep it lower than what would give the titanium coating.
How would this work on a car?
Would it protect the paint or would it chip off as a powder coat would over time?
Try aluminum tape as a masking material. It's often used in systems to coat samples to be used in electron microscopes and it's dirt cheap as duct tape alternative. We used it in our electron beam welders too.
Try making your titanium coils, tighter, touching, as well. It has an effect on how hot or how cool the coil gets. Look at some Vape coil making videos, to show you what I'm talking about.
this channel makes my brain into big brain
When you're wrapping a coil that way, wrap it tight.
2. Squish your tight wrap even tighter while it's on the rod.
Then pull your coil to desired spacing while it's on the rod.
This works unbeleivably well.
This will evenly heat the coil and reduce titanium wire consunption
