Title:  Advanced environmental barrier coatings for SiCf/SiC composite

Abstract:  The materials of emerging engine hot-section components are focused on SiCf/SiC composite with environmental barrier coating (EBC) that can withstand harsh thermal and chemical attacks from combustion environment. Typical EBCs provide reliable protections to SiCf/SiC components below the surface temperature of 1300℃. However, the present EBCs demonstrate limited capability of corrosion resistances to hot steam and molten CaO-MgO-Al2O3-SiO2 (CMAS) deposit at higher temperatures, as well as the phase instability and amorphization during coating fabrication. To address these critical challenges, new strategy is developed to design advanced rare-earth silicate EBCs with multilevel optimizations, including both multicomponent (or high entropy) rare-earth modification and microstructure regulation. The advancement of new multi-RE-component silicate EBCs may support the advancements of SiCf/SiC composite engine components for future requirements.
