Nickel plating is a process of coating a metal object with a thin layer of nickel. There are two main types: electrolytic (also called electroplating) and electroless. Electrolytic nickel plating uses an electric current to deposit nickel from a solution, while electroless plating uses a chemical reaction to achieve the same result. Both methods offer benefits like corrosion resistance, improved appearance, and increased wear resistance. Electrolytic Nickel Plating: 1. Pre-treatment: The object
