Study of Nickel-Plating Electrolysis Process on Mild Steel Material

Nickel plating is used for decorative, engineering, and electroforming purposes. The typical base metals for nickel plating are steel, copper alloys, and zinc alloys. Steel and copper alloy substrates are usually plated directly, but copper underplating is required for plating on zinc. Stainless steel, aluminum, magnesium, and plastics can also be nickel plated, but they require special treatment before plating. Nickel coatings for engineering applications are usually smooth and matt, while the decorative coatings are lustrous, smooth, and bright. Bright nickel coatings are plated with thin chromium coating to prevent nickel tarnishing
