Nickel electroplating is a similar technique of electro-finishing as compared to Zinc. A thin layer of nickel is electro-deposited onto a metal object. The nickel layer can be decorative, provide corrosion resistance, wear resistance, or used to build up worn or undersized parts for salvage purposes. Parts to be plated must be clean and free of dirt, corrosion, and defects before plating can begin. Once the piece has been prepared it is immersed into an electrolyte solution and is used as the cathode. The nickel anode is dissolved into the electrolyte in form of nickel ions. The ions travel through the solution and deposit on the cathode.
