被覆切削工具
Document Type and Number:
Japanese Patent JP6844704
Kind Code:
B2
Abstract:
A coated cutting tool of the present invention is a coated cutting tool having a hard coating film on a surface of the tool. The hard coating film is a nitride containing aluminum (Al) within a range of 80 at% to 90 at% and containing titanium (Ti) within a range of 10 at% to 20 at% with respect to a total amount of metallic (including metalloid) elements, and containing argon (Ar) of 0.50 at% or less with respect to a total amount of the metallic elements (including metalloid) and nonmetallic elements. In the hard coating film, a crystal structure identified through X-ray diffraction is a hexagonal closest packing structure and a diffraction peak due to an AlN (100) plane indicates a maximum intensity. An average crystal grain size is within a range of 5 nm to 50 nm. In a cross-sectional observation of the hard coating film, there are five or fewer droplets having an equivalent circle diameter of 1.0 µm or larger per 100 µm2.
