Nickel coating, or nickel plating, is the process of coating an item with a nickel alloy, generally nickel phosphate.

Applications of Nickel Coating
Nickel coating is used in many industries, including aerospace, automotives, chemical processing, and electronics. Nickel coating can be used to prevent oxidation or improve the surface finish of an item.
Process of Nickel Coating
Nickel coating often employs an electroless method, sometimes called chemical plating, which does not use electricity. Electroless nickel coating involves several simultaneous reactions in an aqueous solution. Various nickel-phosphorus alloys are used in nickel plating. Alloys with high phosphorus content (10 to 15%) add to nickel’s ductile and non-magnetic qualities. Low-phosphorus alloys (1 to 5%) are required for items that are to be welded or brazed.
