Title (EN) SURFACE COATED CUTTING TOOL AND MANUFACTURING METHOD THEREOF
(FR) OUTIL DE COUPE À REVÊTEMENT DE SURFACE ET SON PROCÉDÉ DE FABRICATION
(JA) 表面被覆切削工具およびその製造方法
Abstract:
(EN) In a surface coated cutting tool provided with a substrate and a coating formed on the substrate, the substrate is a cemented carbide or cermet, and the surface of the substrate includes a rake face, a flank face, and a cutting edge which connects the rake face and the flank face. In the substrate, the oxygen concentration at a depth position of 0.4 μm from the cutting edge is less than or equal to 1 at%. The coating includes a hard layer, and the absolute value of the compressive stress of the uppermost layer of the hard layer is greater than or equal to 1.5 GPa.
(FR) Cette invention concerne un outil de coupe à revêtement de surface pourvu d'un substrat et d'un revêtement formé sur le substrat, le substrat étant un carbure cémenté ou un cermet, et la surface du substrat comprenant une face de coupe, une face de rabotage, et un bord de coupe qui relie la face de rabotage et la face de flanc. Dans le substrat, la concentration en oxygène dans une position de profondeur de 0,4 µm à partir du bord de coupe est inférieure ou égale à 1 % at. Le revêtement comprend une couche dure, et la valeur absolue de la contrainte de compression de la couche supérieure de la couche dure est supérieure ou égale à 1,5 GPa.
(JA) 基材と、基材上に形成された被膜とを備える表面被覆切削工具であって、基材は、超硬合金またはサーメットであり、基材の表面は、すくい面と、逃げ面と、該すくい面および該逃げ面を繋ぐ刃先面とを含む。基材において、刃先面から0.4μmの深さ位置での酸素濃度は1原子%以下である。被膜は、硬質層を含み、硬質層のうちの最上層は、絶対値が1.5GPa以上の圧縮応力を有する。
