Electroless Nickel Plating

Electroless Nickel plating is a method in which parts are plated not through the running of an electrical current through a part, but instead by a chemical reaction.

Electroless nickel plating is a process that deposits an alloy of 90% nickel and 10% phosphorus on a wide range of metals. The deposition process does not use electricity to drive the plating; instead, this type of electroless plating uses chemical reduction to drive the metal plating process. This results in a uniform coating thickness throughout the entire geometry of the plating part.

Electroless nickel plating offers several benefits. This process operates without the use of electricity and therefore is strictly chemical based. In this process, the bath solution triggers a chemical reaction that binds the nickel to the other components outer layer.

Some benefits of electroless nickel plating are:

• Higher corrosion resistance
• Wear resistance
• Reduced cost
• Uniform thickness
• Easy to machine if needed
• Can be baked hardened to a 60+ Rockwell
• Close tolerance control

Medium phosphorous electroless nickel – Medium phosphorous treatment has a high speed deposit rate and offers bright and semi-bright options for corrosion resistance and cosmetic applications. The processing is very stable and is the most common type of electroless nickel applied.
