Abstract:
The invention relates to a metal substrate coated at least partially with a layered structure. The layered structure comprises an intermediate layer deposited on the metal substrate and an amorphous carbon layer deposited on the intermediate layer. The amorphous carbon layer has a Young's modulus lower than 200 GPa. The intermediate layer comprises a tetrahedral carbon layer having a Young's modulus higher than 200 GPa. The invention further relates to a method to reduce the wear on a counterbody of a metal substrate coated with a tetrahedral carbon coating.
