How can I cover aluminium or other metals with copper oxide using electrolysis? Answered

I am looking for a way of getting CuO (red oxide) over another cheap metal using less copper as possible

Copper has (if I remember) two different oxides. Black copper oxide, made by the action of ammonia solution on copper, is a powder that could coat a surface. ~Bob~

I'm getting blue with ammonia. I get black with hydrogen peroxide or lots of heat.

Yes, initially, you get blue. I flattened copper wire and let it soak in janitor strength ammonia for a month or so. I wanted copper oxide for thermite experiments.

For the question you asked Kiteman has given you the best answer, ShutterBugger hasn't told you how to cover metal with copper oxide using electrolysis. And ammonia won't oxidise copper to black oxide anyway.
jtobako has given a method for coating copper with copper oxide

Oh cack, I should have noticed that. It's a good piece of work! You're looking to improve it I guess? As a suggestion, post a Forum topic pointing to your I'ble asking for exactly what it is you want. Forum Topics tend to get a bit more attention than Answers which are more of the moment.

Forum it. This answer is probably out of sight to anyone that hasn't commented on it & yourself.

You can't. You can, however, coat it with pure copper and then oxidise it.
