Nickel
plating intended for corrosion protection is used to protect iron, copper,
or zinc alloys against corrosive attack in rural, industrial or marine
atmospheres depending upon the thickness of the nickel deposit or is used
as an undercoat for chromium or one of the precious metals. Also used
for decorative purposes.
Nickel plating intended for engineering purposes is used for wear resistance,
abrasion resistance and such incidental corrosion protection of parts
as the specified thickness of the nickel plating may afford. Heavy deposits
of the plating, especially when the Watts bath process is employed, may
be used for build up of worn or undersized parts, or for salvage purposes,
and to provide protection against corrosive chemical environments.
