| 摘要 |
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.
