Publication number: 20230126815Abstract: A coated tool includes a base and a coating layer on the base. The coating layer includes a first layer including Al2O3 particles, and a second layer on the first layer. The second layer includes, sequentially from the base, a first film, a second film in contact with the first film, and a third film in contact with the second film. The first to third films individually include Ti. The first film, the second film and the third film individually include at least one kind selected from C and N. The coated tool satisfies a relationship of a first N content>a third N content>a second N content, in which the first N content is an N content in the first film, the second N content is an N content in the second film, and the third N content is an N content in the third film.Type: ApplicationFiled: March 24, 2021Publication date: April 27, 2023Inventors: Yuusaku SUGAWA, Hayato KUBO, Kenji KUMAI, Hiroyuki KINJO
