Abstract:
(EN) A membrane (12) provided in this surface-coated cutting tool (10) has an α-Al2O3 layer that contains a plurality of α-Al2O3 crystal particles. The area A1 occupied by coarse-grained crystal particles A constitutes 50% or less of an α-Al2O3 layer color map comprising 15μm2 of a machined surface parallel to the surface of the α-Al2O3 layer. The area A2 occupied by (001)-plane-oriented crystal particles is 90% or more of the area A1, while the area B1 occupied by medium-grained α-Al2O3 crystal particles B is 20-50%, inclusive, of the area A1. The area B2 occupied by (001)-plane-oriented crystal particles is 90% or more of the area B1, while the area C1 occupied by fine-grained α-Al2O3 crystal particles C is 10-50%, inclusive, of the area B1. The area C2 occupied by (001)-plane-oriented crystal particles is 50% or more of the area C1. The proportion of the combined surface area of the area A1, the area B1, and the area C1 relative to the surface area of the entire color map is 95% or higher.
(FR) Un film de revêtement (12) dont est équipé l’outil de coupe à surface revêtue (10) de l’invention possède une couche α-Al23 contenant une pluralité de grains cristallins de α-Al23. La surface A1 de grains cristallins (A) grossiers dans la couche α-Al23, sur une table des couleurs de 15μm2 relative à une face d’usinage parallèle à la surface de cette couche, est inférieure ou égale à 50%, et la surface A2 de grains cristallins d’orientation de plan (001) dans la surface A1, est supérieure ou égale à 90%. La surface B1 de grains cristallins (B) de α-Al23 intermédiaires, est supérieure ou égale à 20% et inférieure ou égale à 50%, et la surface B2 de grains cristallins d’orientation de plan (001) dans la surfaceB1, est supérieure ou égale à 90%. La surface C1 de grains cristallins (C) de α-Al23 fins, est supérieure ou égale à 10% et inférieure ou égale à 50%. La surface C2 de grains cristallins d’orientation de plan (001) dans la surface C1, est supérieure ou égale à 50%. La proportion de surface totale de la surface A1, de la surface B1 et de la surface C1, par rapport à la surface de l’ensemble de la table des couleurs, est supérieure ou égale à 95%.
(JA)  本発明の表面被覆切削工具(10)が備える被膜(12)は、複数のα-Al23の結晶粒を含むα-Al23層を有する。α-Al23層のうち、その表面に平行な加工面に関する15μm四方のカラーマップにおいて、粗粒な結晶粒Aの占める面積A1が50%以下であり、かつ、面積A1のうち、(001)面配向性の結晶粒の占める面積A2が90%以上であり、中粒なα-Al23の結晶粒Bの占める面積B1が20%以上50%以下であり、かつ、面積B1のうち、(001)面配向性の結晶粒の占める面積B2が90%以上であり、微粒なα-Al23の結晶粒Cの占める面積C1が10%以上50%以下であり、面積C1のうち、(001)面配向性の結晶粒の占める面積C2が50%以上であり、カラーマップ全体の面積に対する、面積A1、面積B1、および面積C1の合計面積の割合が、95%以上である。
