Abstract

A method for producing elongated strip, wire or cable, a portion or all of which is defined by electrically metallic superconducting material. In one form, a substrate in the form of a strip, wire or cable, is formed by extrusion, rolling, drawing, casting or a combination of two or more of such processes, of a metal, combination of metals, metal compound, non-metallic material or a combination of such materials, and is controllably driven through a reaction chamber while the material thereof, or of the surface stratum thereof, is chemically converted, as it is driven, to a superconducting material. In a second form, such elongated wire, strip or cable is controllably coated with one or more materials which define a superconducting layer thereon or a plurality of such superconducting layers which bond or solidify on the substrate. In a third form, such coating or plurality of coatings, is subjected to chemical processing and/or radiation of a nature to consolidate and form a solid layer thereof and, in certain instances, to convert same to a superconducting material or to improve or predeterminately define the superconducting characteristics thereof.
