Abstract:
(EN) A surface-coated cutting tool in which a hard coating layer including at least the three layers of an upper layer α, an adhesion layer β, and a lower layer γ are formed, wherein the upper layer α comprises an α-Al2O3 layer formed in a low-temperature condition, an outermost layer of the adhesion layer β adjacent to an interface thereof with the upper layer α includes at least a TiCN layer having a thickness of at least 0.5 µm, 0.5-3 atomic% of oxygen being contained only to a maximum depth of 0.5 µm toward the inside in the thickness direction of the TiCN layer from the interface between the TiCN layer and the upper layer α, and the lower layer γ comprises a single phase of (Ti1-xAlx)(CyN1-y) in an NaCl-type face-centered cubic structure, the average content ratio Xavg of Al and the average content ratio Yavg of C in the compositional formula satisfying the expressions 0.60 ≤ Xavg ≤ 0.95 and 0 ≤ Yavg ≤ 0.005 (where Xavg and Yavg are atomic ratios).
(FR) La présente invention concerne un outil de coupe à revêtement de surface dans lequel une couche de revêtement dur comprenant au moins les trois couches d'une couche supérieure α, d'une couche d'adhérence β et d'une couche inférieure γ sont formées, la couche supérieure α comprenant une couche α-Al2O3 formée dans une condition de basse température, une couche la plus externe de la couche d'adhérence β adjacente à une interface de celle-ci avec la couche supérieure α comprenant au moins une couche de TiCN ayant une épaisseur d'au moins 0,5 µm, 0,5 à 3 % atomique d'oxygène étant contenu uniquement à une profondeur maximale de 0,5 µm vers l'intérieur dans la direction de l'épaisseur de la couche de TiCN à partir de l'interface entre la couche de TiCN et la couche supérieure α, et la couche inférieure γ comprenant une seule phase de (Ti1-xAlx)(CyN1-y) dans une structure cubique à face centrée de type NaCl, le rapport de teneur moyenne Xmoy d'Al et le rapport de teneur moyenne Ymoyde C dans la formule de composition satisfaisant aux expressions 0,60 ≤ Xmoy ≤ 0,95 et 0 ≤ Ymoy ≤ 0,005 (dans laquelle Xmoy et Ymoy sont des rapports atomiques).
(JA) 上部層α、密着層β、下部層γの少なくとも3層を含む硬質被覆層が形成されている表面被覆切削工具において、上部層αは低温条件で成膜されたα-Al層からなり、密着層βは、前記上部層αとの界面に接する最表層は、少なくとも0.5μm以上の層厚を有するTiCN層を少なくとも含み、かつ、前記TiCN層と前記上部層αとの界面から、前記TiCN層の層厚方向の内部へ最大0.5μmまでの深さにのみ0.5~3原子%の酸素が含有され、下部層γは、NaCl型の面心立方構造の単相の(Ti1-xAl)(C1-y)からなり、この組成式におけるAlの平均含有割合XavgおよびCの平均含有割合Yavgは、0.60≦Xavg≦0.95、0≦Yavg≦0.005(Xavg、Yavgは原子比)を満足する。
