| titleOfInvention | A kind of hard alloy piece and preparation method thereof with diamond coatings |
| abstract | The present invention provides a kind of hard alloy pieces with diamond coatings, including hard alloy substrate, and it is set in turn in silicon carbide layer, silicon carbide-diamond gradient composite coating and diamond coatings in described matrix, in the silicon carbide-diamond gradient composite coating, through-thickness is from the silicon carbide layer to the diamond coatings, and carborundum content gradually decreases and diamond content gradually increases.The present invention is by depositing silicon carbide layers first on hard alloy substrate and silicon carbide-diamond gradient composite coating as middle layer, redeposited diamond coatings, so that not only ingredient changes the entire coating of matrix surface in gradient from matrix to top layer, increase without new interface, and thermal expansion coefficient in gradient changes, to which the thermal stress in diamond thin be effectively reduced, film binding force is improved.The present invention also provides the preparation methods of the hard alloy piece with diamond coatings. |
