Scratch resistant electrically conductive aluminum coating
2001
I need a conductive coating on aluminum that resists scratches. I have tried gold Alodine, ( AMSC5541 both class 1A and 3), but they get scratched just by sliding parts on a desk. Is there something more scratch resistant? Would a Chromate work? Or is Chromate just a misnomer for Alodine?

Chromate is not a misnomer, it's a generic name for the MIL-C-5541 process. Alodine is one brand name. Aluminum can be electroplated with whatever metal would meet your needs, but that would be a far more expensive process than chromating.  Ted Mooney, P.E.

Electroless nickel works well for this application.
