Development of High-Temperature Coatings and Applications 690478

As the demands for materials with improved high-temperature properties continue, more research is being directed toward combining materials into composites to provide properties not available in a single material. An excellent example is a coated metal where the corrosion and oxidation resistance or other properties of an alloy are improved or modified by a thin layer of ceramic, cermet or other metal bonded to the surface.
Early developments during World War II and continuing research have produced a number of high-temperature coatings which provide a designer with a unique method for extending a specific materials capability.
This paper is a brief review of some ceramic, cermet, and metallic coatings which indicates the scope of the coating development and applications.
