Abstract: A method is disclosed for improving the performance of noble metal catalysts such as platinum in catalyzed chemical reactions where the reduction of oxygen is a rate limiting step. The catalytic activity of the catalyst and thus, the rate of reaction is increased by increasing the electron density of state at the Fermi level of the catalyst. This can be accomplished, for example, by alloying the noble metal catalyst with materials which increase the electron density of state; i.e. by solid solution alloying. Among the elements which may be used are W,V,Mo,Co and Cr.

Abstract: A method and apparatus are provided for inspecting a coated substrate (72) such as a multi-layer coating (70) on a substrate of a turbine airfoil (22). At each of a number of locations along the airfoil (22) a number of frequencies of alternating current are passed through the airfoil. At least one impedance parameter is measured between electrodes (53,54). The measured impedance parameters are utilized to determine a condition of the coating (70).

Abstract: 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.
