ABSTRACT:
A superconducting composite material comprising a superconducting element, coated on its exterior surface with noble or inert metal, in a conductive metal matrix which includes nonsuperconducting fibers. The superconducting element may suitably comprise a filament of 123 metal oxide high temperature superconductor (MOHTSC) material, or other metal oxide superconductive material. The composite structure of the invention overcomes the inherent brittleness of metal oxide-type superconductive materials and the sensitivity to flaws to which MOHTSC materials are suceptible. The noble or inert metal and conductive matrix metal may suitably be applied by MOCVD techniques. A preferred form of the superconducting article of the present invention is a tape comprising a generally planar array of superconductive filaments, for applications such as energy storage devices, power transmission and propulsion systems that require large magnetic fields, transformers, motors, and generators. Also disclosed are a method and apparatus for applying a liquid organometallic compound in atomized form to a substrate which is heated to sufficient temperature to decompose the applied organometallic compound and yield a film of deposited metal on the substrate.
