1 INTRODUCTION Silicon carbide ceramic matrix composites (SiC CMCs) are proposed to replace current generation Ni-base superalloys as hot-section components to increase aero turbine engine operating temperatures, and thereby increase engine efficiency.1-6 However, deleterious reactions occur between the CMCs and water vapor from the hot combustion environment, which prohibit broader use of CMCs in the aeronautics industry.7, 8 Environmental barrier coatings (EBCs) are required to suppress...
