Titanium CarboNitride or Carbo-Nitride (TiCN) is a thin film coating that was developed from Titanium Nitride. TiCN offers slightly higher hardness compared to TiN and can show a slightly lower friction coefficient in many applications. It is primarily used to achieve enhanced abrasive wear resistance. TiCN has a lower temperature limit for service temperature.
