Electroless Nickel Plating Surface Finish for Aluminum Die Cast Components

Electroless nickel plating is an auto-catalytic reaction used to deposit a coating of nickel on a substrate such as aluminum die casting components. Unlike electroplating, it is not necessary to pass an electric current through the solution to form a deposit. This plating technique prevents corrosion and wear. Electroless nickel plating techniques can also be used to manufacture composite coatings by suspending powder in the bath. Electroless nickel plating has several advantages compared to electroplating. EN plating is free from flux-density and power supply issues and provides an even deposit regardless of workpiece geometry. With the proper pre-plate catalyst, EN plating can deposit on non-conductive surfaces.
