摘要： Cutting tool insert has a substrate and a coating with a total thickness of 5 to 40 μm, the coating being one or more refractory layers of which at least one layer is an α-Al2O3 layer having thickness of 1 to 20 μm. The length of Σ3-type grain boundaries in the at least one α-Al2O3 layer is more than 80% of the total length of the sum of grain boundaries of Σ3, Σ7, Σ11, Σ17, Σ19, Σ21, Σ23 and Σ29-type grain boundaries (grain boundary character distribution measured by EBSD). The at least one α-Al2O3 layer is deposited by chemical vapor deposition (CVD) using reaction gases comprising H2, CO2, AlCl3 and X and optional additions of N2 and Ar, with X being gaseous H2S, SO2, HF, SF6 or combinations thereof.

摘要： A coated cutting tool includes a substrate of cemented carbide, cermet, ceramics, steel or cubic boron nitride, a multi-layered wear resistant coating and at least two refractory coating layers deposited. The at least two refractory coating layers include a first coating layer and a second coating layer deposited on top of each other. The first coating layer is titanium aluminum nitride or carbonitride Ti1-uAluCvNw, with 0.2≤u≤1.0, 0≤v≤0.25 and 0.7≤w≤1.15 deposited by CVD. The second coating layer is titanium carbonitride TixCyN1-y, with 0.85≤x≤1.1 and 0.4≤y≤0.85, and is deposited on top of the first coating layer by MT-CVD. The second TixCyN1-y coating layer has a columnar grain morphology and the overall fiber texture of the TixCyN1-y coating layer is characterized by a texture coefficient TC (1 1 1)>2.

The α-Al2O3 layer has a crystallographic preferential orientation characterized by a texture coefficient TC (0 0 12)≧5 for the (0 0 12) growth direction.The α-Al2O3 layer has an inherent stress in the region of 0 to +300 MPas, and the substrate within a region of 0 to 10 μm from the substrate surface has an inherent stress minimum in the region of −2000 to −400 MPas.
