    Abstract: A wear resistant multilayer coating is provided. The wear resistant coating comprises at least one internal layer and a thin, external layer of disordered boron and carbon applied to a substrate. The synergistic interaction of a hard internal layer and a lubricious boron and carbon layer provides a long lived tool coating. In a more specific embodiment, the external layer of the coating is disordered boron carbide. In accordance with one embodiment, the disordered boron and carbon external coating is of a composition B.sub.x C.sub.1-x where x is from about 0.60 to about 0.90.

    Abstract: Disclosed is a method of forming a hard, carbonaceous film on a substrate and the hard carbonaceous film formed thereby. The hard carbonaceous film is formed by decomposing a gaseous hydrocarbon having carbon atoms tetrahedrally coordinated to carbon nearest neighbors through carbon-carbon single bonds. The gaseous hydrocarbon is decomposed in a radio frequency maintained plasma and the plasma decomposition products are deposited on a cathodic substrate. Optionally, fluorocarbons may be present in a decomposition gas.
