摘要： 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.

摘要： An article comprising a non-conductive substrate having a sub-micron thickness of an oxidizable conductive first metal coating thereon, and a second (promoter) metal which is galvanically effective to promote the corrosion of the first metal, discontinuously coated on the first metal coating. Optionally, the second metal-doped, first metal-coated substrate may be further coated with a salt, to accelerate the galvanic corrosion reaction by which the conductive first metal coating is oxidized. Also disclosed is a related method of forming such articles, comprising chemical vapor depositing the first metal on the substrate and chemical vapor depositing the second metal on the applied first metal coating, and of optionally applying a salt by salt solution contacting of the second metal-doped, first metal-coated substrate. When utilized in a form comprising fine-diameter substrate elements such as glass or ceramic filaments, the resulting product may be usefully employed as an evanescent chaff. In the presence of atmospheric moisture, such evanescent chaff undergoes oxidation of the first metal coating so that the radar signature of the chaff transiently decays.

摘要： A method for metallizing a filament, wherein the filament is initially coated with a sol gel dispersion of polysilicate, titania, or alumina, and after drying at elevated temperature to form a porous interlayer coating on the filament, a nickel coating is deposited thereon from gaseous nickel carbonyl in a metallizing zone. The gaseous nickel carbonyl is produced in a fluidized bed of particulate nickel through which carbon monoxide make-up and at least a portion of the effluent gases discharged from the metallizing zone are flowed. The resulting nickel coated filament may be cut into fibers for use as a reinforcement in composite materials such as those utilized in electromagnetic inteference (EMI) shielding applications.
