Black chrome layers are decorative coatings that can be deposited with a deep black lustre. Nickel coatings are primarily used as a base for black chrome plating. However, steels, copper and copper alloys as well as nickel alloys can also be black chrome plated directly.

Black chrome layers are decorative coatings that can be deposited with a deep black lustre. Nickel coatings are primarily used as a base for black chrome plating. However, steels, copper and copper alloys as well as nickel alloys can also be black chrome plated directly.

A black oxide layer with a chromium content of 60 - 70 % and a hardness of 250 - 300 HV is deposited. The black chrome coatings are nowhere near as scratch and wear-resistant as bright chrome coatings, but are as corrosion-resistant as micro-cracked chrome coatings.
