  • Cutting tool for machining metallic materials
    Patent number: 8828563
    Abstract: A cutting tool for metal material processing has a hard metal body and a multi-layer coating applied to the hard metal body in at least one surface area. The multi-layer coating includes the following, sequentially in direction from the hard metal body to the surface of the cutting tool: at least one layer TiCx1Ny1, where x1+y1=1, x1?0, y1>0; at least one layer TiCx2Ny2Oz2, where x2+y2+z2=1, 0?z2?0.03 and 0.5?x2?0.85; at least one layer TiN, or TiCx31Ny31, where 0.2?x31?0.8 and x31+y31=1, or TiNy32Bv32, where 0.0001?v32?0.05 and y32+v32=1; at least one layer: TiNy41Bv41Oz41, where y41+v41+z41=1 and 0.0001?v41?0.05 and 0.01?z41?0.6, or TiCx42Ny42Oz42, where x42+y42+z42=1 and 0?y42?0.5 and 0.01?z42?0.6; and at least one outer layer ?-Al2O3. The at least one layer TiCx2Ny2Oz2 has a texture in the direction having a texture coefficient TC(311)=1.3.
