Electroless nickel plating
is achieved by forming a thin layer of
nickel phosphate on
a solid workpiece such as metals and
plastics. The
thickness of the plating film is usually measured in
micrometers. It is
used in
aviation,
automotive,
electronic
fabrication (HDD), and
printing press
manufacturing among others. This plating technique
is to prevent the occurrence of
oxidation (rust),
to make or restore fine dimension and to improve the
surface finish of a particular component.

| Electroless plating, also
known as chemical or auto-catalytic
plating, is a non-galvanic
type of plating method that involves several simultaneous reactions
in an
aqueous solution, which occur
without the use of external electrical power. The reaction is
accomplished when
hydrogen is released by a reducing
agent, normally
sodium hypophosphite, and oxidized
thus producing a negative charge on the surface of the part. The
most common electroless plating method is electroless nickel
plating. |
Electroless nickel plating has
several advantages versus nickel sulfamate
(electrolytic) plating. Free from flux-density
issues, it provides an even deposit regardless of
workpiece geometry, and with the proper pre-plate
catalyst, can deposit on non-conductive surfaces.
