摘要： A coated tool of the present invention includes a substrate and a hard coating on the substrate. The hard coating is a nitride or a carbonitride containing 65 atom % or more and 90 atom % or less of Al and 10 atom % or more and 35 atom % or less of Cr with respect to a total amount of metal elements including metalloid elements, and containing 0.50 atom % or less of argon (Ar), and has a face-centered cubic lattice structure. The hard coating shows a maximum intensity Ia in an α angle range of 80° to 90° in an X-ray intensity distribution on an α-axis in a positive pole figure of a (111) plane of the face-centered cubic lattice structure, and an intensity in an α angle range of 0° to 70° is 35% or less of the maximum intensity Ia.

摘要： A coated cutting tool includes a substrate and a hard coating film. The hard coating film includes a b layer which is disposed on the substrate, a c layer which is a multilayer coating film laminated on the b layer and in which a c1 layer of a nitride or a carbonitride containing Al and Cr and a c2 layer of a nitride or a carbonitride containing Ti and Si are alternately laminated with a film thickness of 50 nm or less, respectively, and a d layer which is disposed on the c layer and is a nitride or a carbonitride of TiSi. The c layer contains 0.10 atomic % or less of Ar with respect to a total amount of a metal (including metalloid) element and a non-metal element.

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.
