    摘要: A water-cooled stator bar clip for electrical generators and a method for applying a corrosion-resistant protective coating, preferably Sc, Ti, Cr, Zr, Nb, Mo, Hf, Ta, W, Ni, and Al, and their alloys or oxides to existing stator bar end fittings in order to significantly reduce the possibility of leaks through the brazed connections of the copper stator bar end connections. The coatings can be applied locally using various known physical vapor deposition (“PVD”), chemical vapor deposition (“CVD”) or other direct coating techniques known in the art. For example, the coatings can be applied using ion plasma deposition, sputtering or wire arc techniques (all PVD processes) or by using electroplating, high velocity oxygen free (“HVOF”) deposition, DC arc or electroless plating. Preferably, the coatings are applied either to new stator bar clips or to existing clips in the field using a known pencil coater technique. After being deposited, the metallic coatings form a protective oxide layers over the existing copper brazed joint after being exposed to a water environment, thereby protecting the chemical and structural integrity of the underlying copper brazed joint.

    摘要: A solar cell having foil electrodes. Specifically, a metal foil is implemented to form electrodes providing a reduced electron path from a dye-sensitized semiconductor material to the electrodes. In one embodiment, nanowires extending from the substrate on which the solar cell is formed are provided. In another embodiment, cavities are formed in a sheet of conductive foil by oxidation, thereby forming a semiconductive material. The semiconductive material is sensitized with a dye and an electrolyte solution is disposed in the cavities, thereby forming an array of dye-sensitized solar cells.

    摘要: A method for heat treating titanium-alloy articles in a vacuum furnace includes a step of first determining, for a first set of titanium articles in a first vacuum furnace and for a first set of heat treatment conditions, a minimum surface area of the first set of titanium articles associated with an acceptable alpha case formation for the first set of titanium articles. There is a second determining, for a second set of titanium articles in a second vacuum furnace and for a second set of heat treatment conditions, of a minimum surface area of a second set of titanium articles associated with an acceptable alpha case formation for the second set of titanium articles, responsive to the value of the minimum surface area of the first set of titanium articles. There follows a heat treating of a third set of titanium articles in the second vacuum furnace and for the second set of heat treatment conditions, where the surface area of the third set of titanium articles is not less than the value of the minimum surface area of the second set of titanium articles.
