TiCN coating — Industry Glossary Entry
Definition of TiCN (Titanium Carbonitride) PVD coating for industrial blades: a harder and more wear-resistant variant of TiN, ideal for abrasive substrates.
On this page2 sections
TiCN coating Titanium Carbonitride (TiCN) is a PVD ceramic coating, harder and more wear-resistant than TiN, with a blue-grey colour. Applied at 400–500 °C, 2–4 µm thick. The carbon content in the coating structure gives TiCN a higher hardness (2,800 HV vs 2,300 HV) and lower friction than TiN.
When to use
- Abrasive non-woven slitting
- Recycled polymer granulator bed knives
- Glass-filled polymer cutting
- Coated paper slitting
- Corrugated slitting
When NOT to use
- Above 400 °C edge temperature (carbon in the coating oxidises, loses hardness)
- Stainless or aluminium (DLC is better)
- High-temperature cutting (TiAlN, AlCrN better)
