摘要： Some variations provide a process for additive manufacturing of a nanofunctionalized metal alloy, comprising: providing a nanofunctionalized metal precursor containing metals and grain-refining nanoparticles; exposing a first amount of the nanofunctionalized metal precursor to an energy source for melting the precursor, thereby generating a first melt layer; solidifying the first melt layer, thereby generating a first solid layer; and repeating many times to generate a plurality of solid layers in an additive-manufacturing build direction. The additively manufactured, nanofunctionalized metal alloy has a microstructure with equiaxed grains. Other variations provide an additively manufactured, nanofunctionalized metal alloy comprising metals selected from aluminum, iron, nickel, copper, titanium, magnesium, zinc, silicon, lithium, silver, chromium, manganese, vanadium, bismuth, gallium, or lead; and grain-refining nanoparticles selected from zirconium, tantalum, niobium, titanium, or oxides, nitrides, hydrides, carbides, or borides thereof, wherein the additively manufactured, nanofunctionalized metal alloy has a microstructure with equiaxed grains.

摘要： The sintered electrical contact material described in this specification includes at least one salt dispersed within a silver matrix, and no more than 100 ppm of cadmium and cadmium compounds. The sintered electrical contact material exhibit contact resistances much lower than commercially available silver composites. The salts dispersed within the silver matrix represent a new class of additives for silver composites for high and low current applications.

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.
