文摘
- •
Damage of PVD-coated cutting tool during titanium alloy turning was investigated.
- •
TiN coating on cutting tool wore faster than actual cemented carbide tool.
- •
Damage mode of the coating was fracture without plastic deformation.
- •
Coating damage dependent on interfacial strength with adhered materials.
- •
Diagram for explaining coating damage during titanium alloy turning is proposed.
