Abstract
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 TiAlCN, 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 TiCN, 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 TiCNcoating layer has a columnar grain morphology and the overall fiber texture of the TiCNcoating layer is characterized by a texture coefficient TC (1 1 1)>2.
