Filed:

Feb 22, 2008

Appl. No.:

12/035798

Inventors:

Ray Y. Lin - Cincinnati OH, US
Donald E. Stafford - Loveland OH, US

Assignee:

The University of Cincinnati - Cincinnati OH

International Classification:

C22C 5/02
C22C 32/00

US Classification:

75247, 75240

Abstract:

The present invention relates to particle reinforced noble metal matrix composites and a method of making the same. The composites include a noble metal such as silver, gold, and alloys thereof, as a base or matrix, and a particle reinforced filler material, such as a carbide. A pressureless infrared heating, or superheating, process is used to produce the particle reinforced noble metal matrix composites thereby providing a composite with at least sufficient hardness, i. e. wear resistance, and/or low resistivity. The composites may be used in the jewelry industry, such as for making watches, rings, and other jewelry, and/or in the power, automobile, and aircraft industries, such as for making electrical contact materials.

Appl. No.:

8/280300

Inventors:

Ray Y. Lin - Cincinnati OH
Sunil G. Warrier - Cincinnati OH

Assignee:

University of Cincinnati - Cincinnati OH

International Classification:

B32B 506

US Classification:

427299

Abstract:

The present invention provides a method for application of metal coatings, specifically copper and silver, to continuous ceramic fibers, by electroless deposition. The method comprises the steps of: winding the uncoated ceramic fibers over a frame so that the fibers are coiled adjacent to each other; introducing the wound ceramic fibers into a solution of metal with which the fibers are to be coated; circulating the solution through said fibers; and contacting and causing the metal to be deposited on the wound fibers. Coated continuous ceramic fibers produced by the method of the present invention are also included within the scope of this invention.
