| 摘要 |
The present invention relates to a CVD-coated cutting tool insert with a TiC x N y -layer with a low tensile stress level of 50-390 MPa and an ±-Al 2 O 3 -layer with a high surface smoothness with a mean Ra ‰¤ 0.12 µm as measured by AFM-technique. This is obtained by subjecting the coating to an intensive wet blasting operation. |
