A coating and method of depositing it is provided. The wear resistant coating comprises a thin layer of disordered boron and carbon applied to a substrate. The coating has good adherence and provides good resistance to wear so that it is useful as a tool coating. In a more specific embodiment, the coating is disordered boron carbide. The coating can have a high gloss and can also be used as a decorative coating. The coating can be made by sputtering boron and carbon onto a substrate. A bias voltage may be applied to the substrate during sputtering. In accordance with one embodiment, the disordered boron and carbon coating is of a composition B. sub. x C. sub. 1-x where x is from about 0. 60 to about 0. 90.

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.
