Abstract
A method of producing a compacted article according to one embodiment may involve the steps of: Providing a copper/molybdenum disulfide composite powder including a substantially homogeneous dispersion of copper and molybdenum disulfide sub-particles that are fused together to form individual particles of the copper/molybdenum disulfide composite powder; and compressing the copper/molybdenum disulfide composite powder under sufficient pressure to cause the copper/molybdenum disulfide composite powder to behave as a nearly solid mass.

A compacted article comprising a copper/molybdenum disulfide composite powder compressed under sufficient pressure to cause said copper/molybdenum disulfide composite powder to behave as a nearly solid mass, said copper/molybdenum disulfide composite powder comprising a substantially homogeneous dispersion of copper and molybdenum disulfide sub-particles that are fused together to form individual substantially spherical particles of said composite powder.
A compacted article consisting essentially of a copper/molybdenum disulfide composite powder comprising a substantially homogeneous dispersion of substantially spherical copper and molybdenum disulfide sub-particles that are fused together to form individual substantially spherical particles of said composite powder compressed under sufficient pressure to cause copper/molybdenum disulfide composite powder to behave as a nearly solid mass.
A method of producing a compacted article, comprising:
- providing a copper/molybdenum disulfide composite powder comprising a substantially homogeneous dispersion of copper and molybdenum disulfide sub-particles that are fused together to form individual substantially spherical particles of said copper/molybdenum disulfide composite powder;
- and
- compressing said copper/molybdenum disulfide composite powder under sufficient pressure to cause said copper/molybdenum disulfide composite powder to behave as a nearly solid mass.
A method of producing a copper/molybdenum disulfide composite powder, comprising:
- providing a supply of copper metal powder;
- providing a supply of molybdenum disulfide powder;
- combining said copper metal powder and said molybdenum disulfide powder with a liquid to form a slurry;
- feeding said slurry into a stream of hot gas;
- and
- recovering the copper/molybdenum disulfide composite powder, said copper/molybdenum disulfide composite powder comprising a substantially homogeneous dispersion of copper and molybdenum disulfide sub-particles that are fused together to form individual substantially spherical particles of said copper/molybdenum disulfide composite powder.
A copper/molybdenum disulfide composite powder comprising a substantially homogeneous dispersion of copper and molybdenum disulfide sub-particles that are fused together to form individual substantially spherical particles of said copper/molybdenum disulfide composite powder.
A method of producing a compacted metal article, comprising:
- providing a granulated copper/molybdenum disulfide powder comprising a substantially homogeneous dispersion of copper and molybdenum disulfide sub-particles that are aggregated together to form individual substantially spherical particles of said granulated copper molybdenum disulfide powder;
- and
- compressing said granulated copper/molybdenum disulfide powder under sufficient pressure to cause said granulated copper/molybdenum disulfide powder to behave as a nearly solid mass.
A metal article comprising a copper/molybdenum disulfide composite powder formed to a solid mass, said copper/molybdenum disulfide composite powder comprising a substantially homogeneous dispersion of copper and molybdenum disulfide sub-particles fused together to form generally spherically-shaped individual particles of said copper/molybdenum disulfide composite powder in which each particle contains substantially the same amount of molybdenum disulfide.
