Electroless Nickel Plating
Electroless nickel plating is a chemical process that deposits an even layer of nickel-phosphorus alloy on the surface of a solid substrate.
Unlike electroplating, electroless plating processes in general do not require passing an electric current through the bath and the substrate; the reduction of the metal cations in solution to metallic is achieved by purely chemical means, through an autocatalytic reaction.
Nickel plating is a cost-effective and extremely viable alternative to chrome plating. It is corrosion resistant offering excellent wear and can be fortified by extreme heat treatments.
Where chrome plating has poor throwing power meaning that it is often difficult to create a uniform coating, nickel plating creates an even coating on a part’s surface. Nickel plating also has flexibility in plating volume and thickness, which means the plating process can plate recesses and blind holes with stable and uniform thickness.
