NICKEL:
Bright Nickel Plating:
Bright nickel
plating baths use combinations of organic chemical additives to
achieve bright nickel deposits. Bright nickel is used under decorative
chrome and other final finishes to cover small defects such as polishing
lines and to provide luster. Nickel can also be used as a final
finish for certain applications, such as in the plumbing, lighting,
and furniture industries.
Matte (Pearl) Nickel
Plating:
Matte nickel
plating is a uniform finish that is semi-lustrous with low reflectivity.
It is also referred to as pearl or velour nickel; it does not have
the lines or grainy appearance found in traditional satin nickel
finishes. Matte nickel is usually coated with chrome, black nickel
or another final finish. It is used in the plumbing, optical, lighting,
and automotive industries.
Satin (Brushed) Nickel Plating:
Satin nickel plating is a nickel
finish that is semi-lustrous with some reflectivity. It is also
referred to as brushed nickel; it does have lines or a grainy appearance
that is applied by mechanically polishing the surface before or
after the nickel plating. It is used in the plumbing, lighting,
and furniture industries.
Bright Black Nickel Plating:
Black nickel is plated over bright
nickel to give a lustrous black appearance. It is brighter than
black chrome and covers recessed areas better. Since the black nickel
coating is quite thin, corrosion resistance is somewhat limited.
To improve corrosion protection, the black nickel or bright nickel
may be applied over electroless nickel, but the black color may
not hold up in severe environments. It is used for optical components,
gun sights and components, lighting and plumbing fixtures and some
automotive parts.
Matte Black Nickel Plating:
Black nickel is plated over matte
nickel to give a grayish, non-reflective appearance. It is slightly
brighter than black chrome and covers recessed areas better. Since
the black nickel coating is quite thin, corrosion resistance is
somewhat limited. To improve corrosion protection, the matte nickel
may be applied over electroless nickel, but the black color may
not hold up in severe environments. It is used for optical components,
gun sights and components, lighting and plumbing fixtures and some
automotive parts. |
