ABSTRACT:
The present invention uses ion beam assisted deposition to adhere a diamond-like carbon coating to a cobalt-cemented tungsten carbide substrate, resulting in the following gradient at the surface of the substrate: substrate/(metal-silicide or metal-germanide)/(silicon or germanium)/(silicon carbide or germanium carbide)/DLC.
