TiCN
The ceramic coating TiCN can be a range of colours (blue-grey through to pink) depending on the Ti:C ratio. TiCN is a harder ceramic coating and has a lower coefficient of friction than TIN. However it is not a direct replacement for TiN in all applications and is only recommended for cutting, punching, and wear applications where moderate temperatures will be generated.
Successful applications include end mills, reamers, drills, taps, hobs, and carbide inserts. It performs well cutting alloy steels and stainless steels and is used to protect punches, trim dies and blanking dies.
CrN
The ceramic coating CrN has a metallic silver-like colour. CrN is a tough ceramic coating with high hardness, good oxidation resistance, and a low coefficient of friction making it ideal metal forming. CrN is also more corrosion resistant than TiN, especially in aqueous solutions and is used as a direct substitute for chromium plating. The hardness of CrN is approximately 2x that of conventional "hard" chrome plating.
