Advanced environmental barrier coatings (EBC) are being developed to protect SiC/SiC ceramic matrix composites (CMC) used in hot-section components of next-generation gas turbine engines. One of the most reported failure modes of such protections is spallation due to oxidation by water vapor. During operation, water vapor diffuses through the rare earth silicate top coat and reacts with the silicon bond coat to form a silica layer known as TGO (Thermally Grown Oxide). During cooling, the phase transformation of silica from β-cristobalite to α-cristobalite leads to a 4 – 5 % volume contraction. As a result, microfractures appear in the TGO and delamination of the coating occurs upon cycling. This work aims to identify new bond coat compositi...
