  • Patent number: 7282271
    Abstract: A durable protective coating may be formed by applying a thin layer of metastable alumina to a bond coating on a substrate. A thermal barrier coating may then be applied to the metastable alumina and the resulting part may be heat treated to transform the metastable alumina to a mixed alpha alumina having particles of the thermal barrier coating, such as zirconia in the case of an yttria stabilized zirconia thermal barrier coating, dispersed therein. The resulting thermal barrier coating may inhibit microbuckling of the thermally grown oxide scale that grows over time at the thermal barrier coating-bond coating interface.

  • Patent number: 7181915
    Abstract: A high temperature gas turbine component for use in the gas flow path that also is a specular optical reflector. A thin layer of a high temperature reflector is applied to the gas flow path of the component, that is, the surface 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 the 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 high temperature reflector can be applied to any surface aft of the compressor, such as on a centerbody.

  • Patent number: 7172807
    Abstract: The surface-coated member 1 is constituted by coating the surface of the base body 2, made of such a material as cemented carbide or cermet, with the hard coating layer 3 that comprises at least one TiCN layer 4 and the Al2O3 layer 6 formed on the surface of the TiCN layer 4, wherein the TiCN layer 4 is constituted from stringer-like TiCN crystal grown in a direction perpendicular to the base body 2 and mean crystal width w1 of the TiCN layer 4 on the Al2O3 layer 6 side is made larger than mean crystal width w2 on the base body 2 side. This surface-coated member, as a cutting tool, shows excellent breakage resistance and high wear resistance with a long service life, where strong adhesion force of the hard coating layer can be maintained without experiencing peel-off between the TiCN layer and the Al2O3 layer even in cutting operations under harsh cutting conditions, such as intermittent cutting operation where the cutting edge is subject to strong impact.

  • Patent number: 7157144
    Abstract: SrBi2Nb2O9 (SBN) thin films are deposited on Pt/TiO2/SiO2/Si substrates using off-axis pulsed laser deposition technique. Off-axis laser ablation avoids plasma damaging of the surface of SBN thin films and is favorable to grow films along the polarization axis (a–b plane). SBN thin films are grown at 350° C. substrate temperature, with 5 mm away from the plasma focus, and annealed at 750° C. for 1 hour in oxygen ambient. These SBN thin films exhibited giant remnant polarization (Pr) of 50 ?C/cm2 with coercive field of 190 kV/cm. The fatigue endurance of these SBN thin films was measured at 400 kV/cm and showed minimal (<20%) polarization degradation of up to 1010 switching cycles. The leakage current density of SBN thin films was found to be about 2×107 up to an applied field of 100 kV/cm. The above-mentioned properties of off-axis deposited SBN thin films, makes it a good material for NVRAM devices.
