International Classification:

B22F 1/00
B22F 9/18

US Classification:

75255, 75369

Abstract:

Molybdenum metal powder, and method for production thereof. Molybdenum metal powder has surface-area-to-mass-ratios in a range of between about 1. 0 meters/gram (m/g) and about 3. 0 m/g, as determined by BET analysis, in combination with a particle size wherein at least 30% of the particles have a particle size larger than a size +100 standard Tyler mesh sieve. In addition, molybdenum metal powder may be further distinguished by flowability in a range of between about 29 seconds/50 grams (s/50 g) and about 64 s/50 g, as determined by a Hall Flowmeter. A method of producing molybdenum powder may comprise providing a supply of ammonium molybdate, heating the ammonium molybdate at an initial temperature in the presence of a reducing gas to produce an intermediate product, and heating the intermediate product at a final temperature in the presence of the reducing gas, producing molybdenum metal powder.

Abstract:

Molybdenum metal powder has surface-area-to-mass-ratios in a range of between about 1. 0 meters/gram (m/g) and about 3. 0 m/g, as determined by BET analysis, in combination with a particle size wherein at least 30% of the particles are larger than a size +100 standard Tyler mesh sieve. A method for producing molybdenum metal powder includes providing a supply of ammonium molybdate and a reducing gas; causing an exothermic reaction between the ammonium molybdate and the reducing gas at a first temperature to produce an intermediate reaction product and a supplemental reducing gas; causing an endothermic reaction between the intermediate reaction product and the reducing gas at a final temperature to produce the molybdenum metal powder.

Abstract:

A method for producing a metal article according to one embodiment may include: Providing a supply of a sodium/molybdenum composite metal powder; compacting the sodium/molybdenum composite metal powder under sufficient pressure to form a preformed article; placing the preformed article in a sealed container; raising the temperature of the sealed container to a temperature that is lower than a sintering temperature of molybdenum; and subjecting the sealed container to an isostatic pressure for a time sufficient to increase the density of the article to at least about 90% of theoretical density.

Abstract:

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.
