Hastings Metal Finishers. Specialist electroplaters in silver plating, nickel plating, electroless nickel, tin, copper & zinc plating.

Passivation is the process where a relatively active surface that can corrode or stain is deliberately treated with chemicals to convert the surface to a passive one.

Passivation Passivates contain chromium compounds and are used extensively on zinc plated surfaces to extend the useful life of finished components. The colour of the chromate film changes as the film layer becomes thicker, from blue to yellow and through to olive / black.
