Coated cutting tool

Coated cutting tool

A coated cutting tool includes a substrate and a coating. The coating has an α-Al2O3-multilayer of alternating sublayers of α-Al2O3 and sublayers of TiCO, TiCNO, AlTiCO or AlTiCNO. The α-Al2O3-multilayer includes at least 5 sublayers of α-Al2O3, wherein the total thickness of the α-Al2O3-multilayer...

Beschreibung
Zusammenfassung:A coated cutting tool includes a substrate and a coating. The coating has an α-Al2O3-multilayer of alternating sublayers of α-Al2O3 and sublayers of TiCO, TiCNO, AlTiCO or AlTiCNO. The α-Al2O3-multilayer includes at least 5 sublayers of α-Al2O3, wherein the total thickness of the α-Al2O3-multilayer is 1-15 μm and wherein a period in the α-Al2O3-multilayer is 50-900 nm. The α-Al2O3-multilayer exhibits an XRD diffraction over a θ-2θ scan of 20°-140°, wherein the relation of the intensity of the 0 0 12 diffraction peak (peak area), I(0 0 12), to the intensities of the 1 1 3 diffraction peak (peak area), I(1 1 3), the 1 1 6 diffraction peak (peak area), I(1 1 6), and the 0 2 4 diffraction peak (peak area), I(0 2 4), is I(0 0 12)/I(1 1 3)>1, I(0 0 12)/I(1 1 6)>1 and I(0 0 12)/I(0 2 4)>1.
