Electroless Nickel Plating

Electroless nickel plating is an auto-catalytic reaction used to deposit a coating of nickel on a substrate. One of the advantages is that it is not necessary to pass an electric current through the solution to form a deposit. This plating technique is to prevent corrosion and wear. EN techniques can also be used to manufacture composite coatings by suspending powder in the bath.

Electroless nickel plating has other advantages versus electroplating. The process is free from flux-density and power supply issues, it provides an even deposit regardless of workpiece geometry, and with the proper pre-plate catalyst, can deposit on non-conductive surfaces. There are mainly 3 types of Electroless nickel process which is the Low-phosphorus (Low-P), Mid-phosphorus (Mid-P) & High-phosphorus (High-P).
