Document Type and Number:
WIPO Patent Application WO/2024/048757
Kind Code:
A1
Abstract:
The coated tool according to the present disclosure comprises a base body and a coating layer. The coating layer contains a plurality of crystal grains. The plurality of crystal grains have a plurality of regions provided with mutually different crystal orientations. The value of D2/D1 is 0.55-0.95, where, when the crystal orientations of the plurality of crystal grains in the coating layer are analyzed from the planar direction of the coating layer using TEM electronic diffraction mapping and a first crystal grain map and a second crystal grain map are created, D1 is the average grain diameter of the crystal grains derived by taking a weighted average from the first crystal grain map according to area ratio, and D2 is the average grain diameter of the crystal grains derived by taking a weighted average from the second crystal grain map according to area ratio.
