| 摘要 |
A CVD-coated cutting tool insert with a TiCxNy-layer with a low tensile stress level of 10-300 MPa and an alpha-Al2O3-layer with a high surface smoothness of <0.1 mum as measured by AFM-technique is disclosed. This is obtained by subjecting the coating to a first intensive wet blasting operation with a slurry of F80 grits of Al2O3 followed by a second wet blasting treatment with a slurry of F320 grits of Al2O3.
