  • 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.

  • Patent number: 8741011
    Abstract: The present invention relates to a cutting tool insert comprising a body of cemented carbide, cermet, ceramics, high speed steel (HSS), polycrystalline diamond (PCD) or polycrystalline cubic boron nitride (PCBN), a hard and wear resistant coating is applied, grown by physical vapour deposition (PVD) such as cathodic arc evaporation or magnetron sputtering. Said coating comprises at least one layer of (ZrxAl1-x)N with of 0.45<x<0.85 and 0.90?y<1.30 with a thickness between 0.5 and 10 ?m. Said layer has a nanocrystalline microstructure consisting of a single cubic phase or a mixture of hexagonal and cubic phases. The insert is particularly useful in metal cutting applications generating high temperatures with improved crater wear resistance.
