  • Particle reinforced noble metal matrix composite and method of making same
    Patent number: 7608127
    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.
    Type: Grant

  • Large scale metal coating of continuous ceramic fibers
    Patent number: 5681617
    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.
