Low-Cost Protective Layer Coatings on Thermal Barrier Coatings via CCVD
70485 Stimulated by the explosive growth of the turbine industry, there is an increased need for high performance, oxygen barrier materials for extending the lifetime of thermal barrier coatings (TBCs). This project will develop an open-atmosphere Combustion Chemical Vapor Deposition (CCVD) process to synthesize high-quality oxide coatings at low cost. Phase I will demonstrate the viability of the CCVD technique to produce high quality 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 to 1200¿C will be investigated. Commercial Applications and Other Benefits as described by the awardee: The high performance ceramic coatings market was $940 million in 2000, with the aerospace and terrestrial power turbine industry constituting good growth market segments. The CCVD technology should result in oxygen barrier coatings to augment the lifetime of TBCs. Both military and commercial segments should benefit.
