  • Coated cutting tool
    Patent number: 8545997
    Abstract: A coated cutting tool has a substrate and a coating. The coating includes at least one multi-nano-layer having a nano-composite nano-layer formed of crystalline (TixAlyCrz)N and amorphous Si3N4, wherein 0.25?x?0.75, 0.25?y?0.75, 0.05?z?0.2, 0.85?x+y+z?0.97. The atomic ratio of silicon is 1?x?y?z and 1?x?z<0.75 and the thickness of the nano-composite nano-layer is from 1 nm to 100 nm.
    Type: Grant
