摘要： An apparatus and method for manufacturing a ceramic superconductor coated metal fiber (16) comprises a container (12) for holding a nonaqueous solution in which particles of superconductor material are colloidally suspended to form a slurry (14). A voltage source (24) is provided to influence the slurry (14) with an electric field and a magnet device (44) is provided to influence the slurry with a magnetic field. The magnetic field is oriented relative to the fiber to align the superconductor particles of the slurry (14) in a desired orientation for subsequent attachment onto the surface of the fiber (16). The voltage source (24) is connected to the metal fiber to electrically bias the fiber as it is drawn through the slurry (14). Consequently, charged superconductor particles in the slurry attach to the electrically biased fiber. Subsequently, the coated fiber (16) is heated to sinter the aligned particles and establish a ceramic superconductor shell on the metallic fiber substrate.

摘要： A process for depositing a silver coating (18) onto a superconductor (15) involves placing the superconductor (15) into an alcohol solution (30), preferably octanol, which contains silver particles (32). Each silver particle is coated with a layer (38) of oleic acid. An electrode (40), preferably made of silver, is also disposed in the anhydrous solution (30). A direct current voltage is then established on the electrode (40), which causes the silver particles (32) to plate onto the superconductor (15). After electrophoresis, the now-plated superconductor is heated to 900°C for approximately 1 minute.

摘要： A process for joining ceramic superconductor fibres (12) with a channel (14) to fabricate a superconductor wire includes feeding the fibres into the channel (14) and continuously dispensing a flowable solder paste (36) into the channel (14) over the fibres. The combination of channel (14), fibres (12) and solder paste (36) is then subjected to a rapid rise in temperature which sequentially activates the flux in the solder paste (36) and then melts the solder. After the workpiece is cooled and the separated flux has been removed, a superconductor wire has been fabricated.

摘要： A substrate for supporting a ceramic superconductor comprises a metallic base member precoated with an yttrium oxide, rare earth oxide, or zirconium oxide layer and having a constituent oxide former which establishes an oxide layer with the yttrium oxide, rare earth oxide, or zirconium oxide on the surface of the substrate. A layer of ceramic superconducting material covers the substrate with the oxide layer between the metallic base member and the ceramic superconductor layer to inhibit the interdiffusion of respective constituent elements between the metallic base member and the ceramic layer. For applications requiring the transmission of electrical current through the ceramic layer over relatively extensive distances, the substrate can be formed as a wire or ribbon.

摘要： A ceramic superconductor comprises a substantially nonmagnetic preannealed nickel-based alloy substrate which supports a ceramic superconductor. The substrate may include aluminum to strengthen the substrate, make it less magnetic and enhance its chemical compatibility with the ceramic superconductor. The ceramic is formed on the substrate by sintering superconductor grains at temperatures above 1000°C to enhance densification of the ceramic.
