COATED CUTTING TOOL

A coated cutting tool includes a multilayer of alternating sublayers of κ-Al2O3 and sublayers of TiN, TiC, TiCN, TiCO or TiCNO. The multilayer includes at least 3 sublayers of κ-Al2O3. The multilayer further exhibits an XRD diffraction over a θ-2θ scan of 15°-140°, wherein the 0 0 2 diffraction peak...

Beschreibung
Zusammenfassung:	A coated cutting tool includes a multilayer of alternating sublayers of κ-Al2O3 and sublayers of TiN, TiC, TiCN, TiCO or TiCNO. The multilayer includes at least 3 sublayers of κ-Al2O3. The multilayer further exhibits an XRD diffraction over a θ-2θ scan of 15°-140°, wherein the 0 0 2 diffraction peak (peak area) is the strongest peak originating from the κ-Al2O3 sublayers of the multilayer.
