表面被覆切削工具の製造方法
Document Type and Number:
Japanese Patent JP6459073
Kind Code:
B2
Abstract:
A surface-coated cutting tool includes a base material and a coating formed on the base material. The coating includes an ±-Al 2 O 3 layer. The ±-Al 2 O 3 layer contains a plurality of ±-Al 2 O 3 crystal grains and a plurality of º-Al 2 O 3 crystal grains, and has a TC(006) of more than 5 in a texture coefficient TC(hkl). A ratio of C º to a sum of C ± and C º : [C º / (C ± +C º ) × 100](%) is 0.05 to 7%, where C ± is a total number of peak counts of the ±-Al 2 O 3 crystal grains obtained from measurement data of x-ray diffraction for the coating, and C º is a total number of peak counts of the º-Al 2 O 3 crystal grains obtained from the measurement data of the x-ray diffraction for the coating.
