Abstract
(EN) A cutting tool comprising a substrate and a coating film provided upon the substrate, wherein the coating film has a first layer provided on the substrate side and a second layer provided upon the first layer, the first layer consists of a nitride or carbonitride of AlxTi1-x, and the second layer consists of a composite compound including α-Al2O3 and TiSy. Therein, x satisfies the relationship 0.7≤x<1, and y satisfies the relationship 1.0≤y≤2.0.
(FR) L'invention concerne un outil de coupe comprenant un substrat et un film de revêtement disposé sur le substrat, le film de revêtement ayant une première couche disposée du côté substrat et une seconde couche disposée sur la première couche, la première couche étant constituée de nitrure ou de carbonitrure d’AlxTi1-x, et la seconde couche étant constituée d'un composé composite comprenant du α-Al2O3 et du TiSy. Selon l’invention, x satisfait à la relation 0,7≤x<1, et y satisfait à la relation 1,0≤y≤2,0.
(JA) 基材と、前記基材の上に設けられた被膜とを備えた切削工具であって、前記被膜は、前記基材側に設けられた第1層と、前記第1層の上に設けられた第2層とを有し、前記第1層は、AlTi1-xの窒化物又は炭窒化物のみからなり、前記第2層は、α-Alと、TiSと、を含む複合化合物のみからなる。ここで、前記xは0.7≦x<1を満たし、前記yは1.0≦y≦2.0を満たす。
