Benefits of Electroless Nickel Plating: Uniform Coating

The deposit formed by Electroless nickel plating is based on a chemical reaction. Therefore, the deposit collects in equal thickness over all the part, regardless of its shape.  

The alternative, electrolytic plating, relies on an electrical current passing from an anode to the component, the cathode, which is then subject to changes in current density, applicable to its shape. These variations in current density result in variations in deposit thickness.

Therefore, the metal surface finishing process of electroless nickel plating is a more suitable choice for engineering components as it provides the surface with a uniform coating.

Benefits of a uniform coating 

As the components are not deformed by the plating process, the uniformity of the coating obtained by the nickel plating makes the process ideal for engineering components.

Electroless nickel deposits are excellent for corrosion prevention. With regard to the corrosion protection mechanism, the nickel deposit exhibits electro-negative or ‘noble’ behaviour. Therefore, the nickel plating process relies on total encapsulation of the substrate to be effective.

The uniform coating of the nickel plating means that the surface is very hard wearing, resistant to corrosion and durable in a variety of environments. Due to the nature of the chemical reaction, the deposit that forms is an alloy of nickel and phosphorus.

NiTEC are also specialists in diffused nickel plating technology, the copper plating process and the process of shotblasting & heat treatment.
