| 摘要 |
The present invention relates to a coated cutting tool comprising substrate and a coating, wherein the coating comprises a layer of MTCVD TiCN, and a layer of α-Al_2O_3, wherein the α-Al_2O_3 layer exhibits an X-ray diffraction pattern, as measured using CuKα radiation, the (hkl) reflections used are (012), (104), (110), (113), (116), (300), (214) and (0 0 12), and the TC(0 0 12) is higher than 5 and a full width half maximum (FWHM) of a rocking curve peak of the (0 0 12) plane of the α-Al_2O_3 is lower than 30 degrees. |
