ABSTRACT:
A method for protecting a titanium aluminide substrate against environmental degradation at higher temperatures, which comprises applying a layer of a ductile titanium alloy to at least one exterior surface of the substrate and applying an oxidation resistant coating to the exterior surface of the ductile layer. The titanium aluminide substrate may be monolithic or a fiber-reinforced composite structure. The oxidation resistant coating is an ion-plated coating of (a) a noble metal, such as gold or platinum, or (b) a coating of tungsten followed by an ion-plated coating of a noble metal.
