Chromium nitride, CrN is a metallic silver-like coloured coating. CrN is a tough coating with relatively high hardness, good oxidation and corrosion resistance, and a reasonably low coefficient of friction for a ceramic coating. This makes it ideal for forming applications. Due to it’s high corrosion resistant it is used as a direct substitute for chromium plating. The hardness of the CrN coating is approximately 2x that of conventional “hard” chrome plating.

The CrN coating is particularly suitable for use machining copper based materials.
