ABSTRACT:
The present invention provides a method for coating a metal alloy component of a medical implant, particularly a component of a heart valve made of a titanium base alloy, with a strongly adhered coating of diamond-like carbon. The method uses ion beam assisted deposition to form a gradient at the surface of the titanium alloy comprising metal alloy/metal-silicide/(silicon or germanium)/silicon- or germanium-carbide/DLC.
