How to do professional quality black oxide finishing in the home workshop.

- Black Oxide is a chemical process that converts the surface of a steel part to a black oxide and allows it to be impregnated by a thin layer of oil which prevents it from rusting. Since the oil is in the surface it no longer feels oily to the touch. The oil in the black oxide layer prevents it from rusting. In this video I will show you how to do professional quality black oxide finishing in the home workshop. Black oxide is normally only available as a commercial process but there are now kits available for use in the home workshop. Black oxide is very common on nuts and bolts this is because the process does not change the size of the parts which is very important with threaded fasteners. The impregnated oil also helps to prevent surface galling. In my opinion black oxide is ideal for tools and machine parts that are not directly exposed to the elements. The black oxide does not provide indefinite corrosion resistance but for things like tools and machine parts that spend there life in a dry workshop then it is an excellent option.

Always good to hear a fellow UK creator. Subscribed!
Glad you enjoyed it and thanks for the support.
Superb video, once again, from you. Thank you so much!
That was excellent, very clear demonstration and lucid explanation. Thanks for negotiating the discount. I will get one of these kits.
Thanks Carl. Glad you enjoyed it and find the kit useful.
Great demonstration. Will be tuning into more of your videos.
Thanks very much. Glad you enjoyed it and welcome to the channel.
Thanks for a great video Rob. Just ordered the kit using the discount code.
My pleasure. I'm glad you enjoyed it. Hope the kit serves you well.
Thanks. Have just finished a project with a lot of parts to blacken, so this is very timely. Coincidentally am bidding on the same clamp on ebay too.
Excellent, Glad I could help. Thanks for watching.
Nice one Rob!
Cheers Andy. Glad you enjoyed it.
You should clip a TH-cam short out of this and use Paint It Black by The Rolling Stones for the soundtrack
Good 👍
In the USA, Caswell Plating sells black oxide kits and chemicals.
Excellent. I'm glad there are international options. Thanks for sharing.
Caswell Plating do the same in Australia, AUD $125 for the five litre kit
Lancashire farm, good man.
Thank you, Glad you enjoyed it.
Thanks Rob, I’ll have to look for a kit here in Australia.
Cheers Carl. I'm sure you will find one. Try searching for: Black oxide, Black Phosphate, cold blue and gun blue. They are all very similar.
Caswell have the kits here in Aus.
@@SneakyMcBastard I'm sure that firm in the UK would ship to Australia. Hope you guys are doing OK down there in these tricky times.
It looks like a little strainer basket thing with a handle (a kitchen item) would really come in handy here. You see them in Asian markets in many sizes, from "cup" size to "Ramen Restaurant" size. I don't know what the sizes are! But it seems like one could be easily found that would fit into the yoghurt container say, and eliminate all that fishing around. This seems to be working! Rust is a major awful issue where I live, so of course I'm interested.
Great idea, thanks for sharing. Like the basket you put the chips in before they go in the fryer. Dammit.. now I want chips..
The process and resulting finish are also known as bluing. (See Wikipedia, for example.) The color (colour) is, admittedly, often more black than blue. Bluing solutions/kits are available as gun supplies in the USA.
will this work on my vitage sewing machinee parts like the faceplate etc
Thanks for the excellent vid! Do the chemicals last beyond the one job? If so, how much can you get out of a kit?
Hi Bill, Yes they do. The manufacture of the kit estimates approximately 3-4 m2 per litre of solution. So approx 1-2 m2 out of the 0.5l kit I use in the video. You can get different size kits and also just get refills of the individual chemicals as they get used up. There is a good FAQ on their website. www.black-it.co.uk Glad you enjoyed the video and thanks for the support.
Does this work over surface treatments such as chrome items
I have a question on this , if i was doing this to a golf putter that requires lettering to be paint infill , should i do the paint infill and allow to dry b4 i dip in the oil bath ?
How would I go about blacking just the flat of a blade? Will coating the bevels in wax work or am I better off blacking the whole blade and then sanding the bevels back?
Thanks for the review. Shame they don't ship outside the UK. Does it create a layer of Fe2 O3 iron oxide?
As far as i'm aware yes, but i'm not that informed on the exact chemistry. If you are looking for a kit outside the UK try searching these keywords. Black oxide, Black Phosphate, cold blue and gun blue. They are all very similar. Hope that helps, and thanks for watching.
@@Handmadeextreme Thanks, appreciate the tips, and of course, the videos
What does the blacking solution contain?
Is it work on stainless steel?
If black oxide is applied to a motorcycle head and cylinder (cast iron) , how long is it expected to hold up?
Are this possible hot black oxide this formula??
👍😎👍
Cheers. Glad you enjoyed it.
Where can we avail this?
Hi!
Do you know the method how to remove this kind of a black coat ?
I would like to remove the black coating from my bicycle frame but i can't find how to do it properly without sanding.
Not that I am aware of sorry. I'd probably use something like a flapping disc on a grinder to whip off the top surface.
You can just do it by hand using a ScotchBrite pad, the maroon one would do the job well.
If you can't find a kit in your country you can boil your steel parts in water to which about three cups of Ammonium Nitrate has been added. Be warned to add the nitrate *only* in a well ventilated area as it gives of copious amounts of ammonia gas. Boil for as long as it takes for the parts to go black. Also be aware the authorities may have a heightened level of interest in your affairs.
Will be getting this,, BUT I have a number of questions / comments , not to criticize , but to help . You mention not to cross contaminate the chemicals , But with the rinse in the same water there will be , how ever so slight ,,,, a cross contamination of the chemicals & delusion with water with every dip to each bucket ... , I spent years doing nital etching to detect burns on gear teeth after grinding , part of that process is clear water rinse in running water , quick dip in alcohol that dried fast & leaved the part clean for the next dip in the next bucket,,,, a low pressure air gun can speed the process , but don't blow in the direction of the other buckets ,,,
Great comment Randy, Thanks. It's always great to learn from other people experience.
The finish doesn't come anywhere near that of traditional methods and it also wears off very quickly .

What's the point of washing the parts between the baths, if you use the same water?
I tried this kit, the results weren’t great it wasn’t a thick black finish and rather a thin black finish and what scares me more is that the chemicals in this kit are labelled as cancer causing chemicals stating not to breath in the fumes or get on you’re skin, for the health risk factor to finish ratio I wouldn’t bother to try this again
Only in U.K.? So my money isn't green enough?
Stupid using of commercial "Mixture A, B, C" without minimum chemistry known! Scrap!
