Zinc Plating Metal Finishing

Zinc Plating is the electro deposition (galvanizing or electrogalvanizing) of zinc or zinc alloys (eg Zn/Ni, Zn/Sn) to provide corrosion protection. A protective chromate is applied after the zinc, providing a greater protective finish depending on the color type of chromate applied.

Zinc plating is the most common and economical type of plating. Most fasteners and hardware that are found in the local hardware store have been zinc plated. It is available in clear (silver color), blue, yellow, black and olive drab green. KEYWORDS for this process: electroplating
