Title (EN) A COATED CUTTING TOOL
(FR) OUTIL DE COUPE REVÊTU
Abstract:
(EN) The present invention relates to a coated cutting tool comprising a substrate of cemented carbide and a coating, the cemented carbide comprising WC and a binder phase comprising one or more of Co, Fe and Ni, the carbon content in the cemented carbide is a substoichiometric carbon content SCC wherein -0.13 wt%≤SCC<0 wt%, or -0.30 wt% ≤SCC≤ -0.16 wt%, and wherein the coating comprising one or more layers (A) being a metal carbide, metal nitride or metal carbonitride, the metal being at least one of Zr and Hf, optionally Ti is present in an amount of at most 10 at-% of the amount metal, and an aluminum oxide layer, the one or more layers (A) being situated between the substrate and the aluminum oxide layer.
(FR) La présente invention concerne un outil de coupe revêtu comprenant un substrat de carbure cémenté et un revêtement, le carbure cémenté comprenant du WC et une phase liante comprenant un ou plusieurs éléments parmi Co, Fe et Ni, la teneur en carbone dans le carbure cémenté étant une teneur en carbone sous-stœchiométrique (SCC) telle que -0,13 % en poids ≤ SCC < 0 % en poids ou -0,30 % en poids ≤ SCC ≤ -0,16 % en poids. Le revêtement comprend une ou plusieurs couches (A) de carbure métallique, de nitrure métallique ou de carbonitrure métallique, le métal étant au moins l'un parmi Zr et Hf, du Ti étant éventuellement présent en une quantité d'au plus 10 at. % de la quantité de métal, et une couche d'oxyde d'aluminium, la ou les couches (A) étant situées entre le substrat et la couche d'oxyde d'aluminium.
