As new materials for next-generation aircraft engines, SiC/SiC ceramic matrix composites (CMCs) are thought to be promising. The CMCs possess higher thermal resistance and lower density than those of conventional metallic materials. However, when exposed to oxidative steam environment, SiC/SiC CMCs will reduce the thickness resulting from oxidation reactions. Therefore, environmental barrier coatings (EBCs) are necessary to protect the surface of CMC components from water vapor. EBCs without cracks or pores are required so that water vapor will not reach the surface of CMC substrate. As a new deposition process, suspension plasma spraying (SPS) process is expected to produce much denser EBCs since much smaller powders can be supplied in this process. At the same time, however, SPSed powders are easily influenced by residence time in the plasma flame, resulting in evaporation of particular materials and phase transition of feedstock powders. In this study, SiO2-rich Yb silicate suspensions are applied to compensate for the evaporation of SiO2 during the process. Subsequently, the applicability of SiO2-rich SPSed EBCs was discussed.
