摘要： A coated tool of the present invention includes a base material; and a hard coating film on the base material. The hard coating film is a nitride or carbonitride which contains aluminum (Al) of 65 atomic % or more and 90 atomic % or less and titanium (Ti) of 10 atomic % or more and 35 atomic % or less with respect to a total amount of metal (including metalloid) elements, and have a face-centered cubic structure. In the X-ray intensity distribution of the α axis of the positive pole figure with respect to the (111) plane of the face-centered cubic structure, the hard coating film have a maximum intensity Ia in the α angle range of 80° to 90° and an intensity in the α angle range of 0° to 70° is 30% or less of the Ia.

摘要： A coated tool of the present invention includes a base material and a hard coating film on the base material. The hard coating film is a nitride or carbonitride containing aluminum (Al) of 65 atomic % or more 90 atomic % or less, titanium (Ti) of 10 atomic % or more 35 atomic % or less, a total of aluminum (Al) and titanium (Ti) of 85 atomic % or more, and argon (Ar) of 0.20 atomic % or less. The hard coating film satisfies a relationship of Ih×100/Is≤12 when a peak intensity of a (010) plane of AlN of a hexagonal close-packed structure is Ih and a sum of peak intensities due to predetermined nine crystal planes of TiN and AlN is Is in an intensity profile obtained from a selected area diffraction pattern of a transmission electron microscope.
