Title (EN) SURFACE-COATED CUTTING TOOL HAVING EXCELLENT ADHESION-INDUCED CHIPPING RESISTANCE
(FR) OUTIL DE COUPE REVÊTU EN SURFACE AYANT UNE EXCELLENTE RÉSISTANCE À L’ÉCAILLAGE INDUIT PAR L’ADHÉRENCE
(JA) 耐溶着チッピング性にすぐれた表面被覆切削工具
Abstract:
(EN) The purpose of the present invention is to provide a surface-coated cutting tool having an excellent adhesion-induced chipping resistance against chipping induced by adhesion, even in intermittent cutting such as milling performed on a Ti alloy or a stainless steel alloy, etc., which are work materials in which adhesion easily occurs. A surface-coated cutting tool in which a hard coating layer comprising a monolayer or laminated layers is formed on the surface of a tool base made of a WC-based cemented carbide, wherein the surface-coated cutting tool has two to ten zirconium oxide layers measuring 0.03 to 1.8 μm in thickness and 0.1 to 10 μm in width in at least the region extending 50 μm into a rake part from a honing part at the interface between the tool base and the hard coating layer, and, furthermore, the surface-coated cutting tool has a compressive residual stress in the aforementioned region of the rake part of 1000-1900 MPa.
(FR) L'objectif de la présente invention est de fournir un outil de coupe revêtu en surface ayant une excellente résistance à l'écaillage induit par adhérence contre l'écaillage induit par l'adhérence, même lors d'une découpe intermittente telle qu'un fraisage effectué sur un alliage de Ti ou un alliage d'acier inoxydable et autres, qui sont des matériaux de travail dans lesquels l'adhérence se produit facilement. Un outil de coupe revêtu en surface dans lequel une couche de revêtement dur comprenant une monocouche ou des couches stratifiées est formé sur la surface d'une base d'outil constituée d'un carbure cémenté à base de WC, l'outil de coupe revêtu en surface ayant deux à dix couches d'oxyde de zirconium mesurant 0,03 à 1,8 µm d'épaisseur et 0,1 à 10 µm de largeur dans au moins la région s'étendant sur 50 µm en une partie de râteau à partir d'une partie de rodage au niveau de l'interface entre la base d'outil et la couche de revêtement dur et, en outre, l'outil de coupe revêtu en surface a une contrainte résiduelle de compression dans la région susmentionnée de la partie de râteau de 1000-1900 MPa.
(JA) 溶着を発生しやすい被削材であるTi合金やステンレス合金等に対するフライス切削等の断続切削加工においても、溶着に起因するチッピングに対してすぐれた耐溶着チッピング性を有する表面被覆切削工具を提供すること。 WC基超硬合金の工具基体表面に、単層あるいは積層を含む硬質被覆層が形成されてなる表面被覆切削工具において、前記工具基体と前記硬質被覆層の界面の少なくともホーニング部からすくい部50μmまでの領域において、厚み0.03~1.8μm、幅0.1~10μmの酸化ジルコニウム層を2~10個を有する、表面被覆切削工具、および、さらに、前記すくい部の前記領域における圧縮残留応力が、1000~1900MPaである、表面被覆切削工具。
