Objective is to apply CMZP and Mg-Al{sub 2}TiO{sub 5} as coatings to SiC to improve corrosion resistance under coal combustion atmospheres as well as to improve high temperature mechanical properties. The research will also study the mechanism of coal combustion corrosion of SiC at 1000-1400 C. 16 figs, 8 tabs
