    Abstract: Disclosed is a single crystal alloy consisting essentially of, by weight, 0.06-0.09% carbon, 0.016-0.035% B, 0.2-0.4% Hf, 0-0.02% Zr, 6.5-8.5% Cr, 0.4-1.0% Mo, 5.5-9.5% W, 1.2-3.1% Re, 8-10% Ta, 0.3-1.0% Nb, 0-0.4% Ti, 4.7-5.4% Al, 0.5-5.0% Co, 0.1-5% Fe, and the balance of Ni and unavoidable impurities. The alloy is free from solidification cracks during casting a large-sized blade of gas turbines, has grain boundary strength sufficient for assuring the reliability during operation, and further has excellent oxidation resistance to a high combustion gas temperature while having excellent high-temperature strength comparable to that of a conventional single crystal alloy.

    Abstract: A vacuum pump is provided in which gas molecules in a vacuum chamber are sucked and exhausted by the rotational motion of a rotor rotatably supported in a pump case. At least one nickel alloy layer is disposed on a surface of at least one component defining a flow path in the vacuum pump for increasing a resistance of the component to corrosion due to a corrosive effect of a gas flowing through the flowpath. A nickel oxide is formed on a surface of the nickel alloy layer and has a higher emissivity than that of the nickel alloy layer for increasing a quantity of heat radiated from the surface of the component when the component is heated during operation of the vacuum pump.

    Abstract: A leakage seal for use in a gas path between two relatively rotatable members of a gas turbine comprises a foil layer and a cloth layer. The foil layer has two expansive surfaces, a single one of which is covered by the cloth layer. The leakage seal has a proximal end, a distal end, and a generally flat region between the proximal and distal ends. The proximal end is attached to an associated one of the turbine members. The distal end diverges from the generally flat region so as to define a curved hook, along which the cloth portion is wrapped over the foil layer, when the distal end is viewed in cross-section.
