Electroless Nickel Plating is an electrochemical process that deposits an evenly neutralized layer of nickel-free phosphorous alloy on the internal surface of a metal object, such as plastic or metal and is conducted by professional companies such as Poeton.
In some ways, it is a cross between electroplating and electrodeposition: when electroplating, the metal object is placed under a strong electric field to induce electrochemical reactions, such as formation of hydrogen peroxide, which in turn produces a bright white hot flash. The process of electroless nickel plating, however, uses a different sort of stimulus to induce the coating. An electrical current is passed through the object, inducing the zinc particles to be deposited either singly or in groups, depending upon how the current is manipulated.
Another advantage of electroless nickel plating over other methods of plating is its uniformity. This is very important for use in applications requiring a high degree of uniformity, as in the case of aerospace or vehicle components where exact tolerance to small variations in temperature or pressure is crucial.
Electroplated surfaces can be viewed as “flat” in the sense that no area of the object is under any influence of the plating except the flat areas. Because of the uniformity achieved with this method, the surface is free to accept additives and treatments which would cause the formation of unsightly spots, black streaks, or other irregularities in traditional plating methods.
