  • Patent number: 10428417
    Abstract: A coated cutting tool includes a body and a hard and wear resistant PVD coating on the body, wherein the body is made from a cemented carbide, cermet, ceramics, polycrystalline diamond or polycrystalline cubic boron nitride based materials. The coating includes a first (Ti,Al)-based nitride sub-coating and a second (Ti,Al)-based nitride sub-coating. The first (Ti,Al)-based nitride sub-coating can be a single layer, and the second (Ti,Al)-based nitride sub-coating can be a laminated structure, wherein the first (Ti,Al)-based nitride sub-coating includes a (Ti1-xAlx)Nz-layer where 0.1<x<0.4, 0.6<z<1.2, and wherein the second (Ti,Al)-based nitride sub-coating includes a (Ti1-x1-y1Alx1Cry1)Nz1 layer where 0.5<x1<0.75, 0.05<y1<0.2, 0.6<z1<1.2.

  • Patent number: 10023952
    Abstract: A coated cutting tool and a hard and wear resistant coating for a body include at least one metal based nitride layer. The layer is (ZrxCrl-x-y-zAlyMez)Na with 0.55<x<0.85, 0.05<y<0.45, 0?z<0.20, 0.95<a<1.10, and Me is one or more of the elements: Y, Ti, V, Nb, Ta, Mo, W, Mn or Si. The layer can have a thickness between 0.5 ?m and 15 ?m and be comprisied of a single cubic phase or a single hexagonal phase or a mixture thereof. In an exemplary embodiment, the layer is a cubic phase of a sodium chloride structure. The layer can be deposited using cathodic arc evaporation and is useful for metal cutting applications generating high temperatures.

  • Patent number: 9447491
    Abstract: The present invention relates to a coated cutting tool with a coating comprising a multilayer structure consisting of alternating layers A and B forming the sequence A/B/A/B/A . . . or alternating layers A and B and an intermediate layer C between the alternating layers A and B forming the sequence A/C/B/C/A/C/B . . . . Layer A consists of ZrAlN and layer B consists of TiN. Layer C comprises one or more metal elements from each of layers A and B and is of different composition and structure than layers A and B. A method for forming the coated cutting tool is also provided. The method comprises heat treatment of the coated cutting tool prior to use.
