Abstract:
1. An article for conducting high power electrical current comprising a high conductivity nanocomposite comprised of a base of metal or alloy and a plurality of nanoscale particles dispersed within the base wherein the nanoscale particles are incorporated in a region near a surface of the base in a concentration gradient that decreases in a direction from the surface to an interior of the base, the base having an electrical resistivity less than about 10 microhm-cm and the nanoscale particles having an electrical resistivity less than about 20 microhm-cm and an average diameter of less than 500 nanometers to strengthen the base without substantially reducing the conductivity of the composite as compared with the base.
