ABSTRACT:
The present invention provides metal working tools with metal working surfaces bearing a coating of diamond-like carbon that is strongly adhered to the surface via the following gradient: metal alloy or cobalt-cemented tungsten carbide base; cobalt or metal-silicide and/or cobalt or metal-germanide; silicon and/or germanium; silicon carbide and/or germanium carbide; and, diamond-like carbon.
