Electroplating is a process used to reduce the positively charged ions of a desired material, with the help of an electric current. The process also coats a conductive object with a thin layer of the material, such as a metal. Zinc electroplating is one of the most common forms of electroplating and popular because of its relatively low cost, protective nature and attractive appearance. The coating done through this process gives corrosion protection to ferrous components and it can give colors like gold, black or olive drab finish, by post treatment.

The zinc electroplating process can be used to coat nuts, bolts, washers and automotive parts, such as interior components and gas filters. It also provides an effective undercoat for paints, when high corrosion performance is required. The most widely used zinc plating solutions are acid chloride, alkaline noncyanide, and cyanide, and the most widely used zinc alloys for electroplating are zinc-nickel, zinc-cobalt, and zinc-iron.

With the study of zinc electroplating process by Electrochemical Noise (EN), it was found that the EN generated during the electroplating of large conglomerate zinc deposit has large potential oscillation amplitude and positive potential drift. However, small noise amplitude and little potential drift was seen in the case of compact zinc deposit. Any metal can be plated through zinc electroplating process, but the most common are steel and iron, on which the process offers sacrificial protection.
