Abstract:
A process for applying to a substrate an amorphous coating over which a diamond coating is applied comprising:a. coating said substrate with an intermediate coating having a defined crystalline structure selected from the group consisting of at least one of Ti, Zr, Hf, Fe, Co, Ni, Cr, Mn, Mo, Ta, Nb, Cu, Au, Ag, B, Al and Si;b. converting said crystalline structure of said intermediate coating into an amorphous structure by heating with laser radiation, and after said heating, rapidly cooling said intermediate coating to maintain the amorphous structure created by the heating; andc. depositing over said intermediate coating an outer layer of a synthetic diamond coating by chemical vapor deposition.
