  • CARRIER BODY AND METHOD
    Publication number: 20050132957
    Abstract: The present invention relates to a method and a carrier body for coating cutting tools for chip removal. The carrier body is adapted to be used during coating of cutting tool inserts in a CVD and/or a MTCVD method. The carrier body is at least partially comprised of a material selected from the MAX phase family, i.e. Mn+1AXn (n=1,2,3) wherein M is one or more metals selected from the groups IIIB, IVB, VB, VIB and VIII of the periodic table of elements and/or their mixture, A is one or more metals selected from the groups IIIA, IVA, VA and VIA of the periodic table of elements and/or their mixture, and wherein X is carbon and/or nitrogen.

  • Coated cutting tool insert
    Patent number: 6890632
    Abstract: Coated cemented carbide inserts (cutting tool), particularly useful for milling at high cutting speeds in steels and milling in hardened steels are characterised by a WC—Co cemented carbide containing NbC and TaC and a W-alloyed binder phase and a coating including a first, innermost layer of TiCxNyOz with equiaxed grains, a second layer of TiCxNyOz with columnar grains and at least one layer of Al2O3 composed primarily of the ?-phase.
