摘要： Provided is a coated cutting tool that has a nitride hard coating that contains Ti at 70 at % to 95 at % and Si at 5 at % to 30 at % with respect to the total amount of metallic elements, and Ar at 0.05 at % to 0.20 at % with respect to the total amount of metallic and non-metallic elements, has a NaCl-type crystalline structure, exhibits maximum diffraction peak intensity in the (200) plane, and has an average grain size of 5 nm to 30 nm. When 100 at % is defined as the total of content rates of the metallic elements, nitrogen, oxygen, and carbon in a composition at intervals of 20 nm from a depth of 20 nm to 200 nm from a surface of the hard coating, the content rate of nitrogen is 50.0 at % or more.

摘要： A hard coating film of a coated cutting tool contains Al within a range of 70 at % to 80 at % and Ti within a range of 20 at % to 30 at % with respect to a total amount of metallic (including metalloid) elements, and contains Ar of 0.50 at % or less with respect to a total amount of the metallic elements (including metalloid) and nonmetallic elements. The film has a diffraction peak due to each of a TiN (111) plane, a TiN (200) plane, and a TiN (220) plane of an fcc structure and an AlN (100) plane and an AlN (002) plane of a hcp structure, in which the diffraction peak of the TiN (200) plane indicates a maximum intensity and an intensity of the diffraction peak due to the TiN (111) plane is next thereafter. The average crystal grain size is within a range of 5 nm to 50 nm.

摘要： The present invention discloses a coated cutting tool having a hard coating film on a surface of the tool. The hard coating film is a nitride, the content ratio of titanium (Ti) with respect to a total amount of metal elements (including semimetal elements) is in a range of 70 at % to 95 at %, the content ratio of silicon (Si) with respect to the total amount of metal elements (including semimetal elements) is in a range of 5 at % to 30 at %, and the content ratio of argon (Ar) with respect to the total amount of metal elements (including semimetal elements) and non-metal elements is 0.1 at % or less. The hard coating film has a NaCl type crystal structure and has an average crystal grain size in a range of 5 nm to 30 nm.

摘要： A method for producing a tool coated with a hard coating, the method including the following steps: applying a TiAlN coating layer onto a substrate with a first magnetron sputtering process and applying a TixSi1-xN coating layer onto the TiAlN layer with a second magnetron sputtering process, where x is smaller than or equal to 0.85 and preferably between and including 0.80 and 0. 70 whereas the second magnetron sputtering process is performed with power densities greater than 100 W/cm2 and as such is a HIPIMS process.
