The process of Electroless nickel plating uses an auto-catalytic reaction to deposit a coating of nickel onto metallic, or non metallic surfaces to prevent corrosion and wear.
This electroless process contrasts with conventional electroplating, which passes an electric current through the solution to form a deposit.
Electroless nickel plating has several advantages versus electroplating. Free from flux-density and power supply issues, it provides an even deposit regardless of workpiece geometry. With the proper pre-plate catalyst, it can also deposit on non-conductive surfaces
Electroless nickel techniques can also be used to manufacture composite coatings.
