  • Patent number: 8962147
    Abstract: A powder metal component is made of compacted and sintered powder metal particles such as chromium-containing ferrous-based metal and is porous. Following sintering, the pores are impregnated with relatively smaller particles of ceria and/or yttria. The component is then heat treated and the presence of the impregnated ceria and/or yttria serve as nucleation sites for the formation of desirable oxides, such as chromium oxide, on the surface. The impregnated particles that lie below the protective oxide layer remain available throughout the life of the component in the event the original oxide layer becomes worn or damaged, wherein a renewed protective oxide is formed in such regions due to the presence of the impregnated particles.

  • Publication number: 20130295461
    Abstract: Since pseudo-capacitance transition metal oxides (for example, MnO2) have high theoretical capacitance and are eco-friendly, inexpensive, and abundant in the natural world, pseudo-capacitance transition metal oxides are gaining attention as promising capacitor electrode materials. However, pseudo-capacitance transition metal oxides have relatively low electronic conductivity and limited charging and discharging rates, and a it is therefore difficult to use pseudo capacitance transition metal oxides for high output power applications. If a plating process accompanying a liquid-phase precipitation reaction is performed on a nanoporous metal such as nanoporous gold (NPG) to deposit a ceramic material (for example, MnO2 or SnO2) on the surface of a core metal (for example, NPG), a nanoporous metal-ceramic composite having particular structural characteristics and comprising a metal core part and a ceramic deposition part can be obtained.

  • Publication number: 20120282454
    Abstract: A technique for joining porous foam material, such as graphite, metal or ceramic foam, to a substrate is described. The substrate can be metal, a thermoset plastic or a composite material. The substrate has a melting point below that of the foam material. The two are joined together by using the foam to apply heat locally at the surface of the substrate. Some or all of the foam is heated to the appropriate temperature at or above the melting point of the substrate material. The foam and the substrate are then brought together, with the heat from the foam melting or softening the substrate material so that the substrate material infuses into the pores of the foam. As the foam cools below the melting point temperature, the substrate material solidifies to create a mechanical bond between the foam and the substrate.

  • Patent number: 8197573
    Abstract: Methods and apparatuses for depositing agents relatively deep within pores of bio-char. Bio-char is first produced in an airtight oven by heating biomass feedstock. The bio-char is then cooled and steam is diffused into the pores of the bio-char. The steam-laden bio-char is immersed in a liquid bath containing soluble agents that are to be deposited in the pores of the bio-char. The liquid bath cools the char to below the condensation temperature of the steam, whereupon the condensing steam generates a partial vacuum within the pores, drawing the liquid into the pores. The bio-char is then removed from the liquid bath and dried so that the liquid within the pores evaporates, leaving behind the soluble agent. Accordingly, the invention yields bio-char that has soluble agent embedded relatively deep within its pores.

  • Patent number: 8092914
    Abstract: A heat sink substrate has a composite structure including a three-dimensional network structure of SiC ceramic having pores infiltrated with Si, and has a thermal conductivity of not less than 150 W/m·K and an oxygen content of not greater than 7 ppm. The heat sink substrate is easily allowed to have an increased surface area. Further, the heat sink substrate has a higher thermal conductivity and a coefficient thermal expansion close to that of the SiC. Therefore, the heat sink substrate is superior in the efficiency of heat conduction from a semiconductor device. The heat sink substrate is produced by infiltrating a thermally melted Si into the pores of the three-dimensional network structure in a non-oxidative atmosphere in the presence of an oxygen absorber.

  • Patent number: 8092903
    Abstract: A shaped body, particularly a sorbent shaped body, made of microporous and mesoporous adsorbents and of composite adsorbents is provided for, which shaped body employs a reduced proportion of binding agents. The binding agent added to the shaped body solidifies under the application of force, under which force non-uniformly distributed cavities are formed. The proportion of binding agent on the support forming the wall of the shaped body is higher than the proportion of binding agent inside the shaped body. By using modified alumosilicates and/or aluminum silicates with fluidic action during materials exchange and heat exchange, the shaped body provides for high space-time yields while storing heat and cold.

  • Patent number: 8048494
    Abstract: A hollow diamond shell with a size of a few micrometer to hundreds of micrometer and having a geometrical shape and its fabrication method are disclosed. A diamond film is deposited by a CVD method and porous grits are used as a victim substrate to be etched later, so that the substrate can be easily removed by a capillary phenomenon that an etching solution can be intensively absorbed in a substrate etching process. Thus, a perfect diamond shell with only a plurality of fine pores with a nano size without any conspicuous opening can be obtained. Also, a diamond shell with a small opening of below 10 percent of the surface area of grits can be fabricated by controlling a nuclear generation of diamond particles.

  • Patent number: 8025962
    Abstract: An aluminum-silicon carbide composite suitable for a base plate for power module, having an aluminum-silicon carbide composite, with a front and a rear surface plane, that is a flat plate-shaped silicon carbide porous body impregnated with a metal mainly containing aluminum, and an aluminum layer made of a metal mainly containing aluminum formed only on the front surface plane, wherein the rear surface plane of the composite is exposed to the outside, and the shape of the exposed aluminum-silicon carbide composite is rectangular, optionally having peripheral portions encompassing holes removed. Plating is imparted to the composite by providing an aluminum layer on the rear surface plane. Flatness of the composite is improved by grinding its rear surface so that the composite is exposed to the outside. Warpage after grinding the rear surface, is controlled by controlling the thickness of the aluminum layer.
