    摘要： A method of in situ formation of an aluminum carbon nanotube composite material and an induction motor component produced with such composite. The method includes forming an aluminum-based matrix by mixing a catalyst precursor with an aluminum powder such that a colloidal compound is formed that is subsequently sintered to leave a catalytically-active material formed on the surface of the aluminum powder. A carbon-containing gas is introduced to the composite catalyst that includes aluminum and the catalytic metal so that carbon nanotube reinforcements are grown on the aluminum-based matrix with the assistance of the catalytically-active metal. Additional mechanical processing steps may also include pressurizing, sintering and cold-rolling the aluminum carbon nanotube composite material.

    摘要： Methods of applying aluminum coating layers over copper wires are disclosed. A first method may include applying aluminum powder to the surface of a rod, passing the rod through a first set of compression rolls thereby forcing the aluminum powder into a compacted preform around the rod, and heating the rod covered by the preform at 550° C. to 620° C. Further, the heated preform coated rod is passed through a second set of compression rolls thereby obtaining an aluminum coated copper rod. A second method includes disposing a copper rod inside an aluminum tube having an inner layer formed of brazing aluminum alloy, reducing the diameter of the tube's inner surface to match the copper rod, and heating the composite tube-rod such that the inner layer of the brazing alloy fuses to the rod. Another method includes passing the copper rod through a spray of metallic aluminum.
