Alternate to Zinc - Yellow Chromate
Alternate to Zinc - Yellow Chromate
(OP)
I have a mild steel part that I need to plate for corrosion protection.
In the past I would have gone for zinc plating with yellow chromate. Nowadays however, chromium is viewed as uncouth.
So, suggestions for alternates?

RE: Alternate to Zinc - Yellow Chromate
Electroless nickel,
Co-Sn electroplating,
Trivalent Cr passivation of the zinc plating,
Lacquer over zinc,
Powder coating.
