    摘要： Methods are provided for repairing a defect on a silicon-containing substrate. The method may include applying a powder mixture into the defect of an existing coating on a surface of the silicon-containing substrate, wherein the powder mixture comprises silicon and germanium at a Ge mole fraction of 0.01 to 0.3; and heat treating the powder mixture within the defect at a sintering temperature that is 1150° C. to 1400° C. to form a repaired bondcoat within the defect. Repaired components are also provided that include a repaired bondcoat formed within the defect on the silicon-containing substrate, wherein the repaired bondcoat comprises a silicon-germanium phase comprising a Ge mole fraction of germanium of 0.01 to 0.3 and a Si mole fraction of silicon of 0.7 to 0.99.

    摘要： Coatings comprising metallurgical slag are applied to refractory substrates having molten metal-contacting surfaces to create a chemically active and viscous surface that dramatically increases the ability of the treated substrate to remove slag, dross and other inclusions from a base metal alloy as it passes through or contacts the substrate. The refractory substrates include molten metal filters used by foundries and metal casters such as reticulated ceramic foam, cellular/honeycomb, silica mesh, and others that rely on their physical or sieving ability to remove particulate impurities from the base alloy being cast. The chemically active surfaces significantly increase filtration efficiency through a treatment process tailored to the specific chemistry of the alloy being filtered, such as ferrous metals that include iron, steel and more. Other refractory substrates such as aluminum oxide, magnesium oxide, zirconium oxide, aluminum silicate, silicon carbide (as common with reticulated ceramic foam filters) and the like may also include the coatings.

    摘要： A method of manufacturing a surface-modified carbon material is provided that can form a layer of a metal or the like on the surface in a simple manner and with adhesion performance. The surface-modified carbon material is also provided. The method is characterized by heat-treating a carbon substrate together with a carbon member other than the carbon substrate, the carbon substrate embedded in a surface modifying agent comprising a pyrolytic hydrogen halide generating agent and metal particles containing a transition metal. More specifically, a carbon substrate (2) is embedded in powder (3) containing a pyrolytic hydrogen halide generating agent such as ammonium chloride and metal particles containing a transition metal such as stainless steel, and the carbon substrate (2) is heat-treated together with a carbon member other than the carbon substrate, such as a the graphite crucible (6).
