Electroless nickel plating

Chemical nickel plating consists of applying a layer of nickel without the use of an electrical charge; a chemical reducing agent in the solution being applied triggers a controlled autocatalytic reaction, with a phosphorus codeposition. Electroless nickel plating can also be applied to aluminium alloys (including copper and tungsten) with thicknesses ranging from 2-3μ to 50μ (and above), depending on requirements. Electroless nickel plating has a number of advantages, including deposition of a layer of the desired thickness that is far more uniform than can be achieved with electroplating.
