Electroless Nickel Plating is a nickel phos alloy deposit plated by chemical reduction, without applying an external electrical current, onto a suitable substrate. Electroless Nickel Plating provides very uniform, hard, lubricious coatings. The deposit uniformity allows plating of various coating thicknesses on any section of a part exposed to fresh plating solution. Grooves, slots, blind holes, threads, and even the inside of tubing can have the same thickness of coating. As a direct result of the deposit uniformity many post-plate finishing steps such as grinding, can be eliminated, thus lowering overall costs. By varying the percentage of phosphorus in the coating, deposits can be produced that exhibit a variety of properties. High phosphorus deposits (> 10% by weight) - yield deposits that are non-magnetic and highly corrosion resistant.
