COATED CUTTING INSERT |
摘要 |
The present invention relates to a body coated with at least one double layer Al2O3-TiC. Because the Al2O3-layer in contact with the TiC layer consists of kappa-Al2O3 or theta Al2O3 an improved adherence has been obtained. A further improvement of the properties is obtained if the body after the coating is heat treated for 0.3-10 hours at 900-1100 .degree.C in protecting gas atmosphere at which initially nucleated kappa- or theta-Al2O3 is transformed to finegrained alpha-Al2O3. |
