Black Chrome (Chromium) Plating is a decorative and durable black finish that offers, conductivity, corrosion resistant, and ultra-violet light resistance.
Newer black chrome plating processes have been developed from a trivalent chrome process. The black color is achieved by alloying other metals with the chromium deposit.
The newer black chrome process plate a smoother, more reflective, dark chrome finish that does not require a post dip for corrosion protection. This metal or plastic plating process provides better coverage of the entire part.
The main advantages of the newer black chrome plating processes are that they do not need to be waxed or oiled to improve the final metal finish.
Dark Chrome Electroplating on ABS/PC can be plated over bright nickel, satin nickel, or dull nickel. Each of these plating combinations will develop a different appearance from a bright shiny black to a dull matte black finish.
The automotive specification calling out Dusk Chrome is a combination of a satin nickel coating and a black chrome finish.
The black finish can appear anywhere from dull to bright depending on surface preparation.
