Electroless Nickel Plating

Electroless nickel plating (EN) is an auto-catalytic chemical technique which is used in order to deposit a layer of nickel-phosphorus or nickel-boron alloy on a solid workpiece, including metal or plastic. The process is reliant on the presence of a reducing agent, such as hydrated sodium hypophosphite (NaPO2H2·H2O) which reacts with the metal ions to deposit metal.
