"Oxygen barrier materials are being developed to increase the life time of thermal barrier coatings (TBCs) in the advanced gas turbine industry. Approaches including oxidation resistant coatings as inner layers between the bond coat and TBCs andprotective/sintering inhibitor layers on TBCs have been explored. Concepts including oxides such as alumina are being considered. Current techniques like chemical vapor deposition (CVD) and sputtering applying these coatings entail high capital andoperating costs, and low throughput. The open-atmosphere Combustion CVD (CCVD) has been used to synthesize high-quality oxide coatings at low cost, and hence, is an attractive alternative. In this Phase I effort, we will demonstrate the viability of theCCVD technique to produce high quality nanolaminate oxygen barrier coatings with tailored microstructures on TBCs. These coatings will be characterized for microstructure, crystallinity, and their performance in high temperature oxidation testing up to1200¿C will be investigated. Industry partners have already been recruited. Successful accomplishment of Phase I will lead to a follow-on Phase II effort where further development and commercialization of coatings will take place. High performanceceramic coatings market was $940 million in 2000, with the aerospace and terrestrial power turbine industry constituting good growth market segments. Successful development of the CCVD technology will res
