According to one method, an article is formed from a niobium silicide composite material which contains a selected amount of germanium. The article is then heat-treated under conditions sufficient to increase the level of germanium in the surface region to at least about 25 atom %, based on the total composition of the surface region. In another embodiment, a germanium-containing material is applied over a niobium-silicide article, and then diffused into the surface region of the article by way of a heat treatment.Type: ApplicationFiled: December 19, 2006Publication date: June 19, 2008Applicant: GENERAL ELECTRICInventors: Bernard Patrick Bewlay, Richard DiDomizio, Pazhayannur Ramanathan Subramanian, Voramon Supatarawanich Dheeradhada, Joseph David Rigney, Ramgopal Darolia
