Title (EN) SURFACE-COATED CUBIC BORON NITRIDE SINTERED BODY AND CUTTING TOOL PROVIDED WITH SAME
(FR) CORPS FRITTÉ DE NITRURE DE BORE CUBIQUE REVÊTU EN SURFACE ET OUTIL DE COUPE DOTÉ DE CE DERNIER
(JA) 表面被覆立方晶窒化硼素焼結体およびこれを備える切削工具
Abstract:
(EN) A surface-coated cubic boron nitride sintered body comprises a substrate, which is a cubic boron nitride sintered body, and a coating film that comes into contact with and covers the substrate. At the interface between the cubic boron nitride in the substrate and the coating film, the Fe content is 1 at% or less, the W content is 1 at% or less, and the O content is 2 at% or less.
(FR) La présente invention concerne un corps fritté de nitrure de bore cubique revêtu en surface comprenant un substrat, qui se présente sous la forme d'un corps fritté de nitrure de bore cubique, et un film de revêtement qui entre en contact avec le substrat et qui recouvre ce dernier. Au niveau de l’interface entre le nitrure de bore cubique dans le substrat et le film de revêtement, la teneur en Fe est inférieure ou égale à 1 % at, la teneur en W est inférieure ou égale à 1 % at, et la teneur en O est inférieure ou égale à 2 % at.
(JA) 表面被覆立方晶窒化硼素焼結体は、立方晶窒化硼素焼結体である基材と、基材に接して基材を被覆する被膜とを備える。基材中の立方晶窒化硼素と被膜との界面において、Fe含有量は1at%以下であり、W含有量は1at%以下であり、かつO含有量は2at%以下である。
