  • Publication number: 20040126488
    Abstract: A method of manufacturing an ionic conductor to improve oxygen ion conductivity that is otherwise reduced by the presence of deleterious impurities comprising silicon or silicon containing compounds. In accordance with the invention a dissolved salt of a dopant consisting of an alkaline-earth metal is applied to an oxygen ion conducting material composed of doped ceria, doped zirconia, or doped lanthanum gallate and having the impurities. The solution can also be applied with equal success to cation salts and oxides used in making the oxygen ion conducting material. The oxygen ion conducting material with the solution applied thereto is thoroughly mixed and then heated to evaporate the solvent and to decompose the alkaline-earth salt and thereby to form said ionic conductor.

    Abstract: A low cost chromide and chromide/aluminide process for moderate temperature applications. A gas turbine engine component is cleaned and coated with a layer of metal, generally chromium or chromium and aluminum, containing paint. The metal containing paint layer is heated to a first temperature for a first period of time in an air environment to volatilize the solvents in the paint. The metal containing paint layer is heated to a second temperature for a second period of time in an oxygen-free atmosphere to volatilize the solvents in the paint. The now metal layer and component are heated to a third temperature for a third period of time to interdiffuse the metal and the metal of the component. The component and diffusion layer are then cooled to ambient temperature.

  • Patent number: 6720074
    Abstract: A series of bulk-size magnetic/insulating nanostructured composite soft magnetic materials with significantly reduced core loss and its manufacturing technology. This insulator coated magnetic nanostructured composite is comprises a magnetic constituent, which contains one or more magnetic components, and an insulating constituent. The magnetic constituent is nanometer scale particles (1-100 nm) coated by a thin-layered insulating phase (continuous phase). While the intergrain interaction between the immediate neighboring magnetic nanoparticles separated by the insulating phase (or coupled nanoparticles) provide the desired soft magnetic properties, the insulating material provides the much demanded high resistivity which significantly reduces the eddy current loss. The resulting material is a high performance magnetic nanostructured composite with reduced core loss.

The non-sintered element body is temporarily sintered to obtain a partially-sintered element body as a semi-finished product of the solid electrolytic body. An outer surface of the partially-sintered element body is dipped into a slurry. The slurry contains surface roughing powder including large and small grains which are mutually differentiated in grain size. Then, the partially-sintered element body with a rough slurry film coated thereon is completely sintered into the solid electrolytic body.

  • Patent number: 6656526
    Abstract: A method for sintering a porous coating on an open-structure substrate, i.e., a substrate with pre-made pores or openings. The open-structure substrate is spread with a coating paste that is prepared with such a viscosity so that the paste will not drip through the pores/openings on the open-structure substrate. The coating paste is then sintered to form a porous layer on the surface of the open-structure substrate. Optionally, the porous coating may be further coated with a catalyst for fuel cell applications.

    Abstract: A single-step heat treating and surface coating process is provided for steel self-piercing rivets for joining 5xxx and 6xxx aluminum panels. In this process, two coats of zinc and aluminum flakes in an inorganic binder are applied to the steel rivets. After each coating, the rivets are heated to set and cure the coats and to achieve the desired microstructure and hardness level for joining 5xxx and 6xxx aluminum panels. The coating curing step combines the heat treatment with surface coating into a single-step procedure.

  • Patent number: 6635339
    Abstract: The disclosed invention relates to the field of ceramics and concerns an open-cell expanded ceramic which may be used in the form of a deep-bed filter, and a process for the production thereof. The primary object is to produce an open-cell expanded ceramic by a simple and economical process. This object is attained by an open-cell expanded ceramic in which the inner cavities, cracks and the porosity of the ceramic members are filled partially or completely by one or a plurality of metal and/or ceramic phases and/or glass phases. The open-cell expanded ceramic is also produced in that during or after sintering the cavities, cracks and the porosity of the ceramic members are partially or completely filled with a melt or a suspension which melt below the melting temperature of the expanded ceramic, have a coefficient of expansion similar to the coefficient of expansion of the expanded ceramic, and a very good wetting capacity, and only react partially or not at all with constituents of the expanded ceramic.
