TiCN can be a range of colours (blue-grey through to pink) depending on the Ti:C ratio. The TiCN thin film coating is harder 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.
TiCN – Applications
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.
