  • Coated cutting tool insert
    Patent number: 9180522
    Abstract: A cutting tool insert for machining by chip removal includes a body of a hard alloy of cemented carbide, cermet, ceramics, polycrystalline diamond or cubic boron nitride based materials onto which a hard and wear resistant coating is deposited by physical vapour deposition (PVD). The coating includes at least one layer of a NaCl-structured (TicAlaCrbMed)(CzOyNx) where Me is one or more of the elements Zr, Hf, V, Nb, Ta, Mo, W and/or Si, 0.10<a<0.60, b+d>0.20, c>0.05, 0?d<0.25, 0.75<x<1.05, 0?y<0.25 and 0?z?0.25 with a thickness between 0.5 and 10 ?m. The layer has a columnar mictrostructure with an average columnar width of <1 ?m, a compressive stress level of ?6 GPa<?<?0.5 GPa and a nanohardness >25 GPa.
