Coated cutting insert. |
摘要 |
<p>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 DEG C in protecting gas atmosphere at which initially nucleated kappa- or theta-Al2O3 is transformed to fine-grained alpha-Al2O3.</p> |
