Copper anodizing
2002
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.

Rest in peace, Ken. Thank you for your hard work which the finishing world, and we at finishing.com, continue to benefit from.
