The process of zinc nickel is an electrolysis process where zinc and nickel will get deposited on metal surface as per ASTM B841,AMS2417. The process combines the coating properties of zinc with the strength, ductility, and corrosion resistance of nickel which develops a clean finish that, in a few cases, is even superior to cadmium. Additionally, it gives extremely long-term cathodic corrosion protection. This can be applied on fasteners ,machined components .As this is a premium coating process service life will be considerably more than other electroplating process.
