  • Disordered coating
    Patent number: 4716083
    Abstract: 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.
    Type: Grant

  • Cross head for internal combustion engine
    Patent number: 4594973
    Abstract: Disclosed is a valve cross head adapted for mechanically translating valve opening impulses from the rocker arm of an internal combustion engine to the valve stem of the internal combustion engine. The cross head has a metal body portion and a ceramic wear pad. The ceramic wear pad includes a chemical vapor deposited transition metal film on the surface thereof whereby to permit adhesion thereof by brazing or soldering between the wear pad and the body portion.

  • Multilayer coating including disordered, wear resistant boron carbon external coating
    Patent number: 4594294
    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.
