Abstract
(EN) This surface-coated cutting tool is provided with a hard coating layer, in which: a TiAlCN layer α (1) containing 70 area% or more wurtzite hexagonal crystal structure and a TiAlCN layer β (2) containing 70 area% or more NaCl face-centered cubic structure are layered, one layer each, onto the surface of a tool substrate, on a tool surface side (S) and on a tool substrate side (B), respectively; the composition of the TiAlCN layer α (1) is 0.70 ≤ xα ≤ 0.95 and 0.000 ≤ yα ≤ 0.010, if represented by (Ti(1-xα)Al)(CN(1-yα)); the composition of the TiAlCN layer β (2) is 0.65 ≤ xβ ≤ 0.95 and 0.000 ≤ yβ ≤ 0.010, if represented by (Ti(1-xβ)Al)(CN(1-yβ)); and the TiAlCN layer α (1) and the TiAlCN layer β (2) satisfy 0.5μm≤ Lα ≤ 10.0 μm and 1.0 μm ≤ Lβ ≤ 20.0μm, if Lα and Lβ are the mean layer thickness.
(FR) L'invention concerne un outil de coupe doté d'un revêtement de surface, doté d'une couche de revêtement dur, dans laquelle : une couche de TiAlCN α (1) contenant 70 % en zone ou plus d'une structure cristalline hexagonale de wurtzite et une couche de TiAlCN β (2) contenant 70 % en zone ou plus d'une structure cubique centrée sur la face de NaCl sont superposées, une couche de chaque, sur la surface d'un substrat d'outil, sur un côté surface d'outil (S) et sur un côté substrat d'outil (B), respectivement ; la composition de la couche de TiAlCN α (1) est de 0,70 ≤ xα ≤ 0,95 et 0,000 ≤ yα ≤ 0,010, si représentée par (Ti(1-xα)Al)(CN(1-yα)) ; la composition de la couche de TiAlCN β (2) est 0,65 ≤ xβ ≤ 0,95 et 0,000 ≤ yβ ≤ 0,010, si représentée par (Ti(1-xβ)Al)(CN(1-yβ)) ; et la couche de TiAlCN α (1) et la couche de TiAlCN β (2) satisfont 0,5 μm≤ Lα ≤ 10,0 μm et 1,0 μm ≤ Lβ ≤ 20,0 μm, si Lα et Lβ sont l'épaisseur moyenne de couche.
