Zinc-Cobalt is one of the alloy plating processes developed in the nineties to replace cadmium and to provide enhanced corrosion resistance. It has greater corrosion resistance than zinc. In salt spray testing the coating will achieve in the range of 500 hours to red rust. Zinc-Cobalt like zinc can be combined with chromates and sealers to increase corrosion resistance and improve the appearance. Current method of application at Hohman Plating is barrel plating.
Chromates used with Zinc-Cobalt are:
