  • Patent number: 7003959
    Abstract: A high temperature splash plate for use in the combustor of a gas turbine engine that also is a specular optical reflector. A thin layer of a high temperature reflector is applied to the surface of the splash plate of the component that forms a boundary for hot combustion gases. The component typically includes a thermal barrier coating overlying the high temperature metallic component that permits the component to operate at elevated temperatures. The thermal barrier coating must be polished in order to provide a surface that can suitably reflect the radiation into the gas flow path. A thin layer of the high temperature reflector then is applied over the polished thermal barrier coating by a process that can adequately adhere the reflector to the polished surface without increasing the roughness of the surface. The surface reflects radiation in the direction of the turbine back into the hot gas flow path. The reflected radiation is not focused onto any other hardware component.

  • Patent number: 6929867
    Abstract: Gallium nitride is grown by plasma-assisted molecular-beam epitaxy on (111) and (001) silicon substrates using hafnium nitride buffer layers. Wurtzite GaN epitaxial layers are obtained on both the (111) and (001) HfN/Si surfaces, with crack-free thickness up to 1.2 m. However, growth on the (001) surface results in nearly stress-free films, suggesting that much thicker crack-free layers could be obtained.

  • Patent number: 6794057
    Abstract: A configuration for laminated antiferromagnetically coupled magnetic recording layers for a magnetic recording medium is described. For this purpose, a stabilization layer (top layer) is put on top of the main magnetic recording layer (middle layer) and another stabilization layer (bottom layer) is put under the main magnetic recording layer. The top layer, middle layer and bottom layer are antiferromagnetically coupled. This configuration can double the antiferromagnetic coupling on the recording layer and thus increase the thermal stability. This configuration can also further reduce the remnant magnetization thickness product (Mr&dgr;), which is critical for low noise media. A traditional or new intermediate layer, underlayer and seedlayer can be used under magnetic layers of the present invention. Further, a tradition or new overcoat and lubricant can be used over the magnetic layers of the present invention.

  • Patent number: 6444530
    Abstract: A method of forming a contact in a flash memory device utilizes a local interconnect process technique. The local interconnect process technique allows the contact to butt against or overlap a stacked gate associated with the memory cell. The contact can include tungsten. The stacked gate is covered by a barrier layer which also covers the insulative spacers.

  • Patent number: 6352788
    Abstract: A thermal barrier coating (TBC) system for components designed for use in a hostile thermal environment, such as the turbine, combustor and augmentor sections of a gas turbine engine. The TBC system employs a thermal-insulating ceramic topcoat that is compatible with known metallic bond coats, such as diffusion aluminides and MCrAlY and NiAl coatings. The ceramic topcoat is formed of zirconia partially stabilized by about one up to less than six weight percent yttria and further stabilized by about one to about ten weight percent of magnesia and/or hafnia, to exhibit improved impact resistance.

  • Patent number: 6287889
    Abstract: An improved gas phase synthesized diamond, CBN, BCN, or CN thin film having a modified region in which strain, defects, color and the like are reduced and/or eliminated. The thin film can be formed on a substrate or be a free-standing thin film from which the substrate has been removed. The thin film can be stably and reproducibly modified to have an oriented polycrystal structure or a single crystal structure. The thin film is modified by being subjected to and heated by microwave irradiation in a controlled atmosphere. The thin film has a modified region in which a line width of the diamond spectrum evaluated by Raman spectroscopy of 0.1 microns or greater is substantially constant along a film thickness direction of the thin film, and the line width of the modified region is 85% or less of a maximum line width of the residual portion of the film thickness.

  • Patent number: 6231999
    Abstract: A heat-resistant transparent glass article is formed with a film stack deposited on a glass substrate, the film stack comprising one or more infrared reflective films each bearing on its surface facing away from the substrate a protective film of niobium metal having a thickness of up to 25 Å and preferably in the range of about 7 Å to 20 Å. A protective film of niobium metal or metal oxide may be formed on the other surface (facing the substrate) of each infrared reflective film. Metal nitride films such as silicon nitride may be employed between neighboring infrared reflective films, and as an outer protective film.

  • Patent number: 6197436
    Abstract: A method for diffusion coating workpieces of ferrous base metals such as carbon steel and cast iron includes the step of weighing and mixing the following components, in powdered form: Chromium 40-50 wt % Ferrochromium 25-37 wt % Tantalum Carbide 0.40-0.65 wt % Vanadium 0.35-0.70 wt % Ammonium Halide 4-5 wt % Aluminum Oxide Remainder The workpieces are preferably degreased and then placed in a container with the mixed components. The container is sealed and heated to a temperature of 1000°-1050° C. The workpieces and the composition are kept at that temperature for a predetermined period, on the order of forty-five minutes or longer, to permit a surface layer of desired thickness to form. The container is then cooled in a conventional cooling chamber and the workpieces are removed. The method produces coatings having good wear and corrosion resistance.
