Patent number: 9162424Abstract: A coated article system includes a substrate and a surface coating on the substrate. The surface coating is formed by depositing individual particles of a composite metal powder with sufficient energy to cause the composite metal powder to bond with the substrate and form the surface coating. The composite metal powder includes a substantially homogeneous dispersion of molybdenum and molybdenum disulfide sub-particles that are fused together to form the individual particles of the composite metal powder.Type: GrantFiled: January 28, 2013Date of Patent: October 20, 2015Assignee: Climax Engineered Materials, LLCInventors: Carl V. Cox, Matthew C. Shaw, Yakov Epshteyn

Patent number: 4778778Abstract: Process for producing sintered aluminum nitride bodies, comprising sintering a relatively impure aluminum nitride powder comprising at least 95% by weight aluminum nitride and having no more than 3% bound oxygen content, no more than 0.6% metal or metal compound impurities, and no more than 0.5% silicon or carbon impurities, the sintering being carried out by heating the aluminum nitride body from room temperature to the sintering temperature at a rate of no more than 250.degree. C. per hour; introducing an inert gas containing from 1 to 4% by volume hydrogen until the temperature reaches 1200.degree. C.; continuing to introduce solely an inert gas as the temperature is further increased to the sintering temperature; sintering the body at a sintering temperature of from 1600.degree. to 1900.degree. C.; and cooling the sintered body at a rate of no more than 300.degree. C. per hour.Type: GrantFiled: June 3, 1987Date of Patent: October 18, 1988Assignee: Keramont Advanced Ceramic Products CorporationInventors: Robert A. Mallia, Carl V. Cox

Patent number: 4162078Abstract: An injectable packing formulation comprising particulate flexible graphite and a suitable liquid lubricant. Such formulation can be used to pack the stuffing box assembly of any pump, valve, expansion joint, or like structure, and is particularly useful at temperatures in excess of 500.degree. F. where other packing materials do not perform satisfactorily. While stuffing boxes filled with conventional injectable packing formulations require frequent re-packing in order to maintain a seal when operated at elevated temperatures, stuffing boxes packed with the packing formulation of the present invention require little or no maintenance even when operated at highly elevated temperatures.Type: GrantFiled: February 1, 1978Date of Patent: July 24, 1979Assignee: Union Carbide CorporationInventor: Carl V.
