SUBSTRATE COATED WITH A LAYERED STRUCTURE COMPRISING A TETRAHEDRAL CARBON COATING |
摘要 |
The invention relates to a metal substrate (11 ) coated at least partially with a layered structure. The layered structure comprises an intermediate layer (14) deposited on said substrate (11 ) and a tetrahedral carbon layer (16) deposited on said intermediate layer. The intermediate layer comprises at least one amorphous carbon layer having a Young's modulus lower than 200 GPa and the tetrahedral carbon layer has a Young's modulus higher than 200 GPa. The invention further relates to a method to improve the adhesion of a tetrahedral carbon layer to a substrate and to a method to bridge the gap in Young's modulus of the metal substrate and the Young's modulus of a tetrahedral carbon coating deposited on said metal substrate. |
