Plating – Copper and Zinc Nickel
Copper Plating is electrolytic plating that deposits a layer of copper onto the substrate. This process is typically used to provide an anti-seize surface, as a mask to prevent carburizing on surfaces during heat treating, and to enhance solderability. Electrolytic Nickel plating deposits nickel onto the metal substrate. This plating provides corrosion resistance, wear resistance and is also used for decorative purposes. Zinc is an electrolytic plating process that acts as a sacrificial coating to protect the substrate from corrosion. A conversion coating of chromate can be applied after zinc plating to increase the level of corrosion resistance.
