Electroless nickel is a hard, silver coloured coating comprised of nickel alloyed with between 4 and 14% phosphorus (our currently offered process containing 7-9%). It is deposited by immersion of parts in a solution of nickel salts and reducing agents at a temperature of 90°C. Although it has the appearance of an electroplated coating, the process is purely chemical, so that deposition is evenly distributed over the part, including internal and external corners.
Electroless Nickel Plating uses a solution that is a nickel phosphorus alloy. Composition of the plating solution can be tailored to suit different applications. We offer a medium phosphorus electroless nickel plating. This is used for corrosion and wear resistance where as high phosphorus electroless nickel delivers a pore free barrier coating protecting the underlying substrate from attack and offering outstanding corrosion protection and chemical resistance. Electroless Nickel plating delivers an even thickness of deposit easily controlled to thickness’s of 50u plus.
The uniformity of coating achieved with Electroless Nickel lends itself to the plating of irregular shaped components, with inside corners and cavities are not too thinly coated and outside corners not too thickly coated. It is extremely resistant to corrosion and therefore suited to plating parts used in harsh environments, such as in the defence, oil & gas, and marine industries. In these applications Electroless Nickel can help extend the life of a part, therefore reducing the costs of replacement and repair.
Currently we can only offer plating on very small articles. Please contact us advising size and quantity before sending any articles for plating in this process. Thank You!
