Studies of Hostile-Environment Degradation and its Mitigation in Ceramic Coatings for Gas-Turbine Engines
Abstract
The funding is for Dr. Nitin Padture. While the CMAS degradation of TBCs and its mitigation have been studied in some detail, that effort has been largely heuristic, and furthermore such effort in the case of EBCs is still in its infancy. To address the scientific aspects of interactions between CMAS and T/EBCs a basic research program is proposed that uses concepts in physical chemistry, microstructural evolution, kinetics, and thermal/mechanical properties to perform comprehensive studies of a wide variety of T/EBC materials and CMASs. The proposed research program integrates experiments and theory/modeling to provide a comprehensive and scientific understanding of CMAS-induced degradation of T/EBCs and its mitigation. The ultimate goal of the proposed research is to be able to predict the interactions between T/EBCs and CMAS over a large composition/microstructure space, and provide guidelines for the design and demonstration of next generation T/EBCs for CMCs.
