Abstract
Official abstract text for this publication.
A coated tool includes a base and a coating layer on the base. The coating layer includes a first layer including Al 2 O 3 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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A coated tool, comprising a base and a coating layer located on the base, the coated tool comprising a first surface, a second surface adjacent to the first surface, and a cutting edge located on at least a part of a ridge part of the first surface and the second surface, wherein the coating layer comprises a first coating layer comprising a first layer comprising Al 2 O 3 particles, and a second layer located on the first layer, the second layer comprises, sequentially from a side of 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 film, the second film and the third film individually comprise Ti, the first film, the second film and the third film individually comprise 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, the third film comprises C and N, and N/(C+N) in the third film is 0.7 or more. 2. The coated tool according to claim 1 , wherein a thickness of the second film is larger than each of a thickness of the first film and a thickness of the third film. 3. The coated tool according to claim 1 , wherein a thickness of the second film is 0.5-1.0 μm. 4. A cutting tool, comprising: a holder which has a length from a first end to a second end and comprises a pocket located on a side of the first end; and a coated tool, the coated tool being located in the pocket, wherein the coated tool comprises a base and a coating layer located on the base, the coated tool comprises a first surface, a second surface adjacent to the first surface, and a cutting edge located on at least a part of a ridge part of the first surface and the second surface, the coating layer comprises a first coating layer comprising a first layer comprising Al 2 O 3 particles, and a second layer located on the first layer, the second layer comprises, sequentially from a side of 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 film, the second film and the third film individually comprise Ti, the first film, the second film and the third film individually comprise 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, the third film comprises C and N, and N/(C+N) in the third film is 0.7 or more.
