Wow I never realised the finish would change the shade that much. Thanks you!
Wow - that was so informative Chris.
Thanks for educating me👍🏻
Thank you for doing this video. Very informative. Keep up the good work.
thanks for a nice clear explanation & demo, this process has a lot of art in the science.
This was very helpful. Thank you for the valuable inf0. Ferrum & Laconico have become my two favorite Titanium knife designers.
Thanks Chris so Cool Ive been wanting to see a video about why you can only get certain colors in the titanium spectrum.
This was truly fascinating.
Very good info. Thank you. In every sample, the brushed was pretty much my favorite.
I can’t believe how good that polished gold looks, I may have to use that in a project😄thanks 👌
Love the video. I've been testing different finishing products on Titanium to see what colors I can come up with.
Thanks bro for sharing. This answered a lot!! Thanks
Although it wasn’t a contest, I would call satin finish the winner.
Amazing! LOVE the 93v Satin and Polished
Just the kind of video I was looking for
Hm. I got a part made of of titanium with a sandblasted surface, I polished one of the faces, and I anodized the piece. The polished surface ended up pink/purple, and the sandblasted surfaces bluish-green. Now that makes sense. Thank you for posting this. Very helpful!
Great, very interesting. Thanks a lot.
The same effect (different colors at the same voltage) goes for different titanium grades! Very unpredictable.
Very interesting subject. It allows to get more colors because of refraction on surface.
Thanks
That was fun and interesting. I tried to anno the back spacer and pocket clip from a gray Crux and got some weird striping on the pocket clip. I was hoping for a minty green but couldn't get it and settled for a bright blue at 78.5 volts. I used Borax for the electrolyte additive mixed into distilled water. The striping is mild but it showed up when I dipped it in Whink rust remover (hydrofluoric acid). I might try a different etchant and electrolyte at some point but I'm afraid if I etch much more I'll lose the blast finish on the parts.
That is interesting. Would not have guessed that would happen
Great video!!
super useful for the uninitiated to get a fast understanding.
Hi Chris . Thanks for sharing l just found the channel . I m the guy who emailed about having a vid with some of the tubers . I seen SaturnsRings channel had some interesting vids
Absolutely fascinating. Never would have known. I'm curious how anodizing would vary on other finishes such as stonewash, blackwash, acidwash, or even a higher grit satin polish or a crazy high mirror polish.
Thank you for a great video. This does explain a lot.
Very cool, I believe it has to do with variability in surface roughness at the nano/micro scale achieved by the different polishing methods. The rougher surfaces on the left give a flatter look because they are scattering the light as opposed to reflecting light directly back to give the shiny appearance seen on the right. As for the differences in color, I am less confident in a potential explanation. I do know that, generally, the colors seen are due to a path length difference in reflected light depending on the thickness of the oxide layer (light reflected from metal vs light reflected from oxide). The thickness of the oxide layer typically ranges from 5-50 nm. Source, if anyone is interested, I am a chemistry PhD student studying nanomaterials as photocatalysts.
I don’t know the extent of your knowledge, but how much do you know about type II anodizing? I know that Lye(NaOH) with a pH of 13 works, but not well- resulting in a gray color. Have you heard of any good chemicals to use when aiming for a black colored ano?
@@realnsfwspeedruns I have no hands on experience with anodizing, so I cannot really help you. However, a quick search shows that type II anodizing specifically refers to use of sulfuric acid as the electrolyte. I do not know that it is possible to get a natural black color for metals like titanium. I do know that when anodizing aluminum any colors must be achieved through use of a dye seeing as the oxide layer itself does not give any color. The good news is the surface roughness from the anodizing means the dye should stick around for a while. Best of luck!
Hey if you have a piece that has a lot of angles and different sized thicknesses, does that impact the coloring?
@@jamesoliger2379 since its diffraction, the color you see depends on the angle, so an irregular surface may look iridescent
Awesome thanks
Thank you
Great Video! I have been doing the exact thing you are here, testing out different finishes. One thing I have been hung up on is etching the titanium before anodizing. Is this needed? It seems you are getting these vibrant colors without a pre treatment like multi-etch etc...
So you mean to say that I could make multi-coloured anodizing just by surface grinding. Well of course. That's radical, though, just polish the part, acid etch the markings, then anodise to get multi coloured finish. Amazing!
What polish do you prefer to get a mirror finish? Some polishes (Mother's for example) leave a protective coat that prevents anodizing
Thanks for the content now il sure thé result its hell better with polish titanium thanks a lot
What is the best way to clean the faced or polished anodized handles without scratching them?
Great Video, thanks for posting! Can you tell us how many Amps you were using? I find I need at least 5-6 to be able to cover an already an existing finish.
Thank you! What can I use to seal the anodized/colored titanium surface?
Very informative video. Thank you. What media did you use to tumble with? I have some satin Ti that I want to darken up but I don't have a bead blasting setup.
I've had trouble getting a good blast, seems to dull the surface a bit, but could be the medium. Have you tried any acid etching? I get great results with that.
👍 Great video
I'm thinking of polishing a 1.25 inch titanium tube.
Where did you get the Anodizing supplies.?
That stuff looks phenomenal 😍
Rob
If someone would want to do a stonewashed brown... So first stonewash and than put it to the oven for heat ano right?
I know this is a slightly older video but can you do this with aluminum for us?
I also watched your video comparing chemical treatments. Have all of these parts been chemically treated the same?
AWESOME :)
Volts X Amps = Watts
Volts are the push (pressure sort of) without knowing one of the other variables it means relatively nothing!
What happens if you cover it with vinyl and etch a name or image into it?
Does it over heat and melt?
I’m getting ready to anodize the fasteners on my bosses 3pc wheels.
I had a lot of things anodized and he did nothing before anodizing them and even when he did the wrong colors he followed that up with a poor removal ....now I can see why they turned out like they did 😕
Do you use any ventilation while doing this? Do you have to worry about fumes?
Hey I have two questions, is anodized titanium non conductive like aluminum is, also is a different quality of titanium change the color when anodized?
Can you revert the high voltage colors back down to a low voltage color?
Do you know where I can find some titanium pieces like those to practice with before I mess with my nice pocket knife?
What media are you using for your tumbler and how long are you tumbling?
You think one can get a super polished finish anodized? Like, I want titanium rings for wedding bands since I like it's material properties a lot, ButI also would like them to be golden (colored) if possible, while also being sure the finish isn't too fragile for everyday use
nice project ...but do you have tabe for coloer volteg
trying to add anodizing to my business what machine would you recommend?
nice broject bro. ...but do you have tabel volteg color
How long does the anodized color last before it wears off?
What is in the nano tank? Chemicals?
I had a satin finished piece that looks vibrant from certain angles but really dull from others, what might be the problem with that?
Hey quick question does anodized polished aluminium need to be clear coated to prevent it from discoloring?
Very informative! Cooool👍👍
What voltage did you use for the blue in the second trial?
Does the thickness of the titanium make any difference to the color?
Can someone tell me what would cause pitting when anodizing? Is the electrolyte solution is to concentrated?
That mat looks like it might make a good grippy micarda
Did you etch the titanium before anodizing?
It’s crazy how the same voltage can have totally different colors and after anodizing for the last few months you learn that there’s way to many variables and can’t always predict the exact color. Where these titanium sheets etched before anodizing? I did my first anodizing job using stencils the other day and it came out great. The only problem I had was that I used aluminum oxide media which I didn’t know at the time causes problems with anodizing due to the aluminum so I’m going to try glass beads next time. What type of media do u use in your blasting cabinet?
We use garnet media in our blast booth rather than Aluminum Oxide.
Ferrum Forge Knife Works wow thanks for the great tip I’ll have to pick some up. This should definitely allow me to step up my anodizing game 👊
@@FerrumForge did you etch the titanium before anodizing?
Can you anodize one piece of titanium with multiple surface finishes?
When I tried to anodize my polished titanium, it did not work well. It did not look like yours. I barely got any color. Any idea why?
hi , I want Military Colours , NATO GREEN AND SAND
How to make these or where I can get these
Hiii sire , could you give me the number of Amp's do you use for the process please
bead blast or sand blast?
Were those etched before anodizing or just straight in after being finished? I'm in the uk and looking to try anodizing at home but most videos seem to have people using Multi-Etch in the USA or Titan Etch in mainland Europe. Both of which aren't really an easy option to get hold of but if you can get the colours like the satin finish or the polished with out it I might just try achieving those finishes first.
I use Multi Etch right before I anodize. It's my last step before anodizing.
hello, do you know the complyfe mods?
they do anodize on titanium vape mods and they also do a like many different colors on a mod, i can not attach the pics of mods here but you can google it and see what am i saying?
just want to know how do they do it.
and got couple of titanium mod and cap which is vape stuffs.. but i want try myself and learn about this.
help me as you are real pro of anodize!!
Bro they made with the same steps, but just the diference is, take the positivo to the tube and negative with a wet sponge with solution, and play with the voltage, thats all
Can anyone anwser if you etch with Whinks Rust Remover does it effect you surface finish?
It does if your soak duration gets past 30 seconds. Whinks has sulfuric acid, which is one of the few acids that will dissolve Ti. It tends to be a cloudy or chalky surface finish that is more pronounced than MultiEtch. But it really cuts through oxides so you can dissolve anodic oxidation with it. Whinks will dissolve CP Ti at faster rate the 6Al 4V so it can do interesting things to pattern welded titanium like timascus and mokuti.
@@elliotwillamson7456 Great information Thanks!
How do I remove the bead blast from my titanium??
polish it
nice project do tou have tabel for colors volteg
can you tell me
What liquid solution do you use. I tried anodising with batteries and had no luck.
We use rust remover as our electrolyte solution. You might not have enough amps from the batteries to anodize a blasted finish.
can you get black if you take the voltage higher?
No it just sort of goes back to a washed out gray
Just re-etch it, the HF in the Whink will remove the thin oxide finish.
There are two patented alloys that will go black, I’m not sure where you would get any though.
What grade of titanium is in the video ?
Grade 5 (6Al4V)
Do you think a tattoo power supply will work for anodiz
In theory, yes it will since it's a DC power supply. However, it looks like a lot of tattoo power supplies have very low voltage. You'll need at least 15V to get bronze and at least 30 to get blue.
@@FerrumForge thank you. I have some wink stain remover on the way so... I'll let you know what happens.
@@jacobokubo7726 how’d it go?
Hi, Is it possible to use ingredients in order and quantities
Yes, it's possible.
This is great! How exactly do you do your satin finish? I really like the color changes for that!
My guess would be sanding by hand to a certain grit using sandpaper.
stated 220 grit in video
How to make them pink?
I turn my supply all the way up ~115-120 volts (which is all the way on mine) and it gives a pastel pink almost. But then again I use whinks and don’t polish. Gonna try that now though. Good luck
The satin seems to always be the most vibrant.. why is that?
Not sure if you said it or if someone else has asked, which grade titanium were you working with in this video?
6Al4V (Grade 5)
No wonder my sandblasted piece came out looking damn weird.
Ultraviolet or blurple 😂
Thank you
Hi, is the support you use to hold the titanium parts made of stainless steel? Hope you'll see my comment...
