Copper anodizing
Is there a process for copper that is similar to that of anodizing for aluminum. Specifically, I seek a coating for electrical copper that has a high dielectric and has a very strong bond (more than typical varnish).

I have never heard of it, and could find nothing about it in a quick literature search. Copper can be chemically oxidized, but I am not aware of doing it with anodic current.

Does a chemical oxidation process meet the mentioned criteria (dielectric and bond)?

I'm pretty sure that copper oxides are too conductive for dielectrics. A fused coating of either glass or PTFE would be much better.
