Title (EN) COATED CUTTING TOOL
(FR) OUTIL DE COUPE REVÊTU
Abstract:
(EN) A coated cutting tool comprising a substrate coated with a multi-layered wear resistant coating comprising a layer of α-Al2O3 and a layer of titanium carbonitride TixCyN1-y, with 0.85 ≤ x ≤ 1.3 and 0.4 ≤ y ≤ 0.85, deposited on the α-Al2O3 layer, wherein the TixCyN1-y exhibits a texture coefficient TC(hkl), as measured by X-ray diffraction using CuKα radiation and θ-2θ scan, the TC(hkl) being defined according to Harris formula (I), wherein I(hkl) is the measured intensity (integrated area) of the (hkl) reflection; I0(hkl) is standard intensity of the standard powder diffraction data according to JCPDS card no. 42-1489; n is the number of reflections used in the calculation, and where the (hkl) reflections used are (1 1 1), (2 0 0), (2 2 0), (3 1 1), (3 3 1), (4 2 0) and (4 2 2); and wherein TC(1 1 1) ≥ 3; and a method for producing such a coated cutting tool.
(FR) Cette invention concerne un outil de coupe revêtu comprenant un substrat revêtu d'un revêtement multicouche résistant à l'usure comprenant une couche d'α-Al2O3 et une couche de carbonitrure de titane TixCyN1-y, où 0,85 ≤ x ≤ 1,3 et 0,4 ≤ y ≤ 0,85, déposée sur la couche α-Al2O3. Le TixCyN1-y présente un coefficient de texture TC(hkl), mesuré par diffraction des rayons X à l'aide d'un rayonnement CuKα et d'un balayage θ-2θ, où TC (hkl) est tel que défini dans la formule Harris (I), I (hkl) est l'intensité mesurée (surface intégrée) de la réflexion (hkl)) ; I0(hkl) est l'intensité standard des données de diffraction sur poudre standard selon la carte JCPDS N°42-1489 ; N est le nombre de réflexions utilisées dans le calcul, et les réflexions (hkl) utilisées sont (1 1 1), (2 0 0), (2 2 0), (3 1 1), (3 3 1), (4 2 0) et (4 2 2) ; et TC (1 1 1) ≥ 3. Un procédé de fabrication dudit outil de coupe revêtu selon l'invention est en outre décrit.
