Black Metal Process ?
Anyone know the name for the process to turn steel black? For instance, an engine cylinder jug like on a VW Beetle? I believe it's some sort of oxidizing process, but not sure.

Hey, Bill, great second book! One way to blacken steel is Parkerizing.

The coating on black bolts used on 50's cars, was black oxide an coated with an oil that air dried. I don't think that would last long on engine parts as the oil would burn off and they would turn to rust! Steve

It could be manganese phosphate you're thinking of...

Does Parkerizing turn things black? I thought it was a dull green like on original military 1911s?

Yes it does. There is another process called "tool black". It's fast and easy but a bit pricey. |

You can turn pretty much anything black, by heating and dropping into sump oil and let air cool.
I tried this process for a Stator cover, but it tarnishes the Alloy rather than going black like Bolts. I have also treated most of my pliers and impact sockets this way to prevent rusting. works great seen as I'm right on the coast.

Houghto black - a hot bath of Houghton Chemical co solution, after solvent washing and rinsing. Black oxide - another hot bath immersion method, not as rigorous as the Houghto. Gun blueing - Hot Gun blueing - cold (will rust after a time) Heating the steel to purple heat, and dropping in boiled linseed oil - remove and let dry - pretty good stuff. Misc other methods, like Caswell and others .... some not so hot, others questionable, have not heard rave reviews about weather-resisting products. gun forums have a lot of chitchat about this - I can check. hope this helps, Bill
