Improving Corrosion Resistance of Rare Earth Zirconates to Calcium-Magnesium-Alumina-Silicate Molten Salt Through High-Entropy Strategy.

The erosion caused by high-temperature calcium-magnesium-alumina-silicate (CMAS) has emerged as a critical impediment to the advancement of thermal barrier coating (TBC). In this study, a series of high-entropy rare earth zirconates, (LaSmDyErGd)(ZrCe)O ( = 0, 0.2, 0.
