High temperature alkali corrosion of dense SiC and Si{sub 3}N{sub 4} coated with CMZP and Mg-doped Al{sub 2}TiO{sub 5} in coal gas. Quarterly report, July 1, 1995--September 30, 1995
SiC samples coated with CMZP and Mg-Al{sub 2}TiO{sub 5}, respectively, were tested in a 100-hour slagging combustion test at the Energy and Environmental Research Center at the University of North Dakota. Results of measurements and analysis indicate that CMZP and Mg-Al{sub 2}TiO{sub 5} coatings improved the high temperature alkali corrosion resistance under coal combustion atmospheres. It is clearly shown that it is important to obtain a homogeneous and crack-free coating and good adhesion of the coating to the surface of the substrate for the best corrosion resistance. Some measures to improve the coating procedure are presented.
