  • Alumina coated cutting tool
    Patent number: 10286453
    Abstract: A coated cutting tool insert includes a substrate of cemented carbide, cermet, ceramics, steel or cubic boron nitride having deposited thereon a coating having a total thickness of 60 ?m, including one or more layers having a wear resistant layer of ?-Al2O3 of a thickness of 1 to 45 ?m deposited by chemical vapour deposition (CVD). The ?-Al2O3 layer includes at least two portions, a first thickness portion and a second thickness portion immediately on top of the first thickness portion. The first thickness portion has an essentially columnar ?-Al2O3 grain structure, and at a transition from the first thickness portion to the second thickness portion the grain boundaries of at least 1 out of 25 neighboring grains of the ?-Al2O3 grains undergo a directional change into a direction that is essentially perpendicular, 90±45 degrees, to the grain boundaries in the first thickness portion.
