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 aluminium 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.

摘要： A surface-coated cutting tool includes a base material and a coating formed on the base material. The coating includes an α-Al2O3 layer. The α-Al2O3 layer contains a plurality of α-Al2O3 crystal grains and a plurality of κ-Al2O3 crystal grains, and has a TC(006) of more than 5 in a texture coefficient TC(hkl). A ratio of Cκ to a sum of Cα and Cκ: [Cκ/(Cα+Cκ)×100](%) is 0.05 to 7%, where Cα is a total number of peak counts of the α-Al2O3 crystal grains obtained from measurement data of x-ray diffraction for the coating, and Cκ is a total number of peak counts of the κ-Al2O3 crystal grains obtained from the measurement data of the x-ray diffraction for the coating.

摘要： A surface-coated cutting tool includes a base material and a coating formed on the base material. The coating includes an α-Al2O3 layer containing a plurality of α-Al2O3 crystal grains. The α-Al2O3 layer includes: a first region made up of an edge ridgeline, a region A of a rake face, and a region B of a flank face; a second region which is a region of the rake face except for the region A and covered with the coating; and a third region which is a region of the flank face except for the region B. The α-Al2O3 layer satisfies a relation b−a>0.5, where a is an average value of a TC(006) in the first region in texture coefficient TC(hkl) and b is an average value of the TC(006) in the second region or the third region in texture coefficient TC(hkl).

摘要： A coating for carbide substrates employs a nanostructured coating in conjunction with a non-nanostructured coating. The nanostructured coating is produced by the addition of a refining agent flow, particular hydrogen chloride gas, during deposition, and may be produced as multiple individual nanostructured layers varying functional materials in a series. The combination of a nanostructured coating and non-nanostructured coating is believed to produce a cutting tool insert that exhibits longer life. Pre-treating the substrate with a mixture of compressed air and abrasive medium prior to coating the substrate and post-treating the coated substrate with a mixture of water and abrasive medium after the coating process is believed to further enhance the wear resistance and usage life of the cutting tool.
