Electroless Nickel Plating

Electroless Nickel Plating, what is that? Electroless plating is an auto catalytic chemical technique used to deposit a layer of nickel phosphorous or nickel boron alloy on a solid work piece, such as metal or plastic. On this process is no need additional electric current because the electric charge is merging from the substance itself. The principle of work of this process is the present of reducing agent, for example hypophospite react with metal ions to deposit metal.

Electroless nickel plating often use in various type of parts to protect against wear and corrosion. Uniform deposit of nickel useful for hydraulic cylinders, worm feeds, gears, bellows, shafts, chain belts and other close filling components.

The quality of electroless nickel plating may not stronger as using Nickel electroplating, but electroless nickel plating will improves the quality of components. Tight manufacturing tolerance can be achieved as the electroles nickel is deposited evenly on the surface of the parts. It can be also used to improve the surface of a component so that it is back within the specific tolerance, and provide a surface that allows post finishes to be carried out effectively and produce bright surface coating.
