  • Sintered cemented carbides using vanadium as gradient former
    Patent number: 7794830
    Abstract: The present invention relates to a cutting tool insert for turning consisting of a cemented carbide substrate and a coating. The cemented carbide substrate comprises WC, binder phase, and vanadium containing cubic carbide phase with a binder phase enriched surface zone essentially free of cubic carbide phase. The thermal properties of the vanadium-containing cubic phase, has turned out to give excellent resistance to thermal cracking of the insert.

  • COATED CUTTING TOOL INSERT
    Publication number: 20080298921
    Abstract: A coated cutting tool insert is disclosed particularly useful for dry and wet machining, preferably milling, in un-, low- and high alloyed steels and cast iron, with or without raw surface zones. The insert is characterized by a WC—TaC—NbC—Co cemented carbide with a W alloyed Co-binder phase and a coating including an innermost layer of TiCxNyOz with columnar grains and a top layer, at least on the rake face, of a smooth ?-Al2O3.
