What is a Copper Plating? - Definition from Corrosionpedia

The copper layer protects the coated sections against diffusion of carbon or cementation within the sections. Copper plating is also used in protective chrome plating, in which copper forms the intermediate plate. Nickel plating is applied over the copper layer on steel, then a thin coat of chromium is applied for effective corrosion resistance.
