Patent number: 4777090Abstract: Disclosed is a coated article having a substrate with an adherent, abrasion resistant carbon coating. In a preferred examplification the coating is substantially transparent to visible light and partially absorbing to ultraviolet light. The coating has a relatively disordered portion at the substrate-coating interface and a relatively ordered portion remote from the substrate-coating interface. The coating is a microwave deposited coating with deposition initially at a low microwave energy, and thereafter at a high microwave energy.Type: GrantFiled: November 3, 1986Date of Patent: October 11, 1988Assignee: Ovonic Synthetic Materials CompanyInventors: Stanford R. Ovshinsky, Russell C. Custer, Arnold Register, James D. Flasck, Daniel P. Durisin, Kenneth Havener

Patent number: 4724169Abstract: Multilayer protective coatings that are applied over a substrate that comprise a plurality of superimposed multilayer units and methods of making the coatings are disclosed. Each multilayer unit contains two or more superimposed thin layers in which at least two layers are compositionally different. The properties of the resulting coating are a combination of the properties of the individual layers. One layer of a multilayer unit may provide hardness or wear resistance and another layer may provide lubricity, for example. The thickness of the individual layers can be related to the microscopic surface relief of the substrate to which the protective coating is applied. One disclosed multilayer unit comprises three layers: an oxidation resistant layer; a nitride layer; and a layer of disordered boron and carbon material.A method of making the multilayer coatings is provided that includes depositing over a substrate a plurality of superimposed multilayer units.Type: GrantFiled: June 24, 1986Date of Patent: February 9, 1988Assignee: Ovonic Synthetic Materials Company, Inc.Inventors: John E. Keem, James D. Flasck

Patent number: 4717632Abstract: Adherence coatings and methods for forming same are provided. Generally, the adherence coatings are utilized in combination with exterior wear-resistant coatings of, for example, at least one non-metallic element and a transition metal.The composition of the adherence coating is selected on the basis of the substrate and exterior coating compositions and generally contain one or more metallic elements. The adherence coating can be applied by sputtering, desirably in a manner to produce a columnar microstructure.Type: GrantFiled: August 11, 1986Date of Patent: January 5, 1988Assignee: Ovonic Synthetic-Materials Company, Inc.Inventors: John E. Keem, James D. Flasck, Richard W. Seguin

Patent number: 4716083Abstract: 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: GrantFiled: September 23, 1983Date of Patent: December 29, 1987Assignee: Ovonic Synthetic Materials CompanyInventors: Erwin Eichen, James D. Flasck

Patent number: 4645715Abstract: Coatings and methods for forming same are provided. Generally, the coatings are wear resistant disordered coatings of at least one nonmetallic element and a transition metal that are deposited on an article surface, such as a tool surface or other surface that is subjected to wear or friction. The resulting tools generally exhibit increased life with excellent lubricity thereby improving the surface finish of workpieces machined therewith.Adherence coatings are provided for achieving improved adherence of the wear resistant coating to the substrate.Type: GrantFiled: March 17, 1982Date of Patent: February 24, 1987Assignee: Energy Conversion Devices, Inc.Inventors: Stanford R. Ovshinsky, John E. Keem, James D. Flasck, Richard C. Bergeron, John E. Tyler
