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.
