Hello.
I'm looking for a home, surface nitriding technique, if that is possible. It's more for a durable surface coloring system, than a hardening scenario.
I know they do that for high end plumbing fixtures and such, but in a million dollar vapor deposit chamber.
Any cool ideas out there? Thanks.

you may consider searching some high voltage hobbyist forums. as the nitriding process involves nitrogen plasma... don't quote me on that. im going on a five year old memory of a discovery channel show.
