Abstract

An environmental coating is applied to the surface of a titanium-base alloy substrate to protect the surface from oxidation, corrosion, erosion, and other damage. The coating is a mixture of a metal and a ceramic, each selected to contribute to the protective function. The proportions of the metal and the ceramic in the coating are selected such that the coefficient of thermal expansion of the coating is about the same as the coefficient of thermal expansion of the substrate.
