Abstract: A method for increasing the surface area of foil electrodes of electrolytic capacitors. A valve metal is deposited by evaporation on a valve metal foil in a low pressure inert atmosphere including oxygen at a pressure one to two orders of magnitude lower than the pressure of the inert gas. The resulting surface is fractal-like. The foil thus treated is suitable as such for use as a cathode. Prior to anodization to produce an anode, a discontinuous layer of a valve metal oxide is deposited on the foil, to preserve the high surface area of the fractal-like surface and otherwise promote the formation of a dielectric coating whose interface with the metal foil has a high surface area.

Abstract: Composite materials are composed of a primary metallic base material, such as a titanium metallic material, metallurgically bonded to one or more secondary materials having desirable thermal conductivity properties and having a coefficient of thermal expansion (“CTE”) that generally matches the CTE of the primary metallic material. An exemplary composite material is composed of a titanium primary material metallurgically bonded to a secondary metal matrix composite material having a high thermal conductivity, such as aluminum silicon carbide. Methods for manufacturing such composite materials are disclosed.

Abstract: A method is provided for physical vapor deposition of ceramic thermal barrier coatings and articles made therefrom Impurity levels in conventional yttria stabilized zirconia source materials have caused undesired spitting (eruptions) due to a combined effect of various impurities thereby requiring relatively low evaporation rates to control the level of spitting during the process. The present method provides a high purity source material having a purity index sufficiently low to result in reduced spitting in the vapor deposition process and to permit in evaporation rates. Reducing the density of the source material has also been found to reduce spitting. The method permits higher processing rates and/or reduced levels of spitting.

Abstract: A thermal barrier coating system for a superalloy substrate is disclosed. The superalloy is preferably of the type that is capable of forming an adherent alumina layer. A bond coat is applied to a local area of the substrate, so that a portion of the substrate remains exposed. The localized area is defined to be the area(s) at which a TBC typically fails first, e.g., the leading and trailing edges of an airfoil, or other area. An alumina layer is formed on the remaining portion of the substrate, and also on the bond coat. A ceramic layer is then applied on the alumina layer. Even if the ceramic material is removed, the localized bond coat remains, and reduces the rate at which the underlying substrate oxidizes. A coated article is also disclosed, as is a system that utilizes a conventional superalloy and aluminide coating with the localized bond coat.

Abstract: The increase of temperature in heat sensitive devices during heat generating conditions is prevented through the absorption of heat, by providing Boric acid in an amount sufficient to effect the required heat absorption. Where the heat generating conditions are generated by a heat generator, separate and distinct from the heat sensitive device, the Boric acid is supported in a position between the heat sensitive device and the heat generator. Where the heat sensitive device is itself the heat generator, the Boric acid is contacted to the heat sensitive device either directly or indirectly.
