摘要： The present invention relates to a method for repairing turbine engine components, such as vanes and blades, which have airfoils. The method broadly comprises removing oxidation debris from portions of the component by blending areas exhibiting thermal barrier coating spall and/or oxidation damage, removing a ceramic insulating layer from the component, and blending surfaces of the component where nicks, dents, and/or cracks are located. If the component has a depleted aluminum zone, the depleted zone is either removed or replenished. Further, a tip portion of the component, if damaged, is restored and tip abrasives are applied to restore the component's cutting ability. Thereafter, a ceramic coating is applied to the component.

摘要： An uncooled turbine outer air is comprised of a combination of monolithic ceramics with high temperature capability and oxidation and creep resistance, and a fiber reinforced ceramic composite with high fracture toughness. In a preferred embodiment of the invention, a fiber reinforced ceramic composite of silicon carbide and aluminum borosilicate is infiltrated by chemically vapor deposited silicon carbide. The infiltration process is continued until the composite develops a monolithic layer of silicon carbide. An additional layer is deposited on the monolithic ceramic to provide additional thermal protection.

摘要： A porous substrate of a fuel cell electrode assembly is formed by producing a fibrous carbon precursor web by means of a conventional wet paper-making process. The precursor web is then dried and saturated with a wet resinous binder which will carbonize when heated. Substantially the entirety of all of the carbon fibers in the web are thus coated with the binder, and substantially all of the inter-fiber junctures in the web will also be coated with the binder. The saturated web is then dried, and heat treated to convert the binder to a glassy carbon which exhibits superior resistance to corrosion.
