Black-chrome-coating - for deep-black surfaces

It is not so common to coat objects with black-chrome. And yet black-chrome coatings do have various decorative as well as material related benefits.

Decorative benefits

  • A black-chrome coating does have a very deep-black colour
  • It convinces with a metallic appearance. Depending on the pre- or post-treatment a dull or shiny surface can be created.
  • Objects do not reflect as much (anti-reflexion coating)

Material related benefits

  • The surface is corrosion-resistant
  • Black-chrome has good heat conductivity and is highly temperature resistant
  • the absorbing power is also high
  • the adherence of lacquers is better on black-chrome, e.g. regarding metallic basic materials

Due to this we use black-chrome in decorative as well as in technical sectors, e.g. medical technology as well as engines and other automotive components.

galvanic process

The coating of black-chrome is a galvanic process. By means of electrode-position chromium-oxide and chromium-hydroxide are deposited on the surface of the work piece. This is how the deep-black surface is created. Usually the precipitation takes place on a nickel-alloy. Nevertheless Black-chrome can also be applied directly onto the object.
