In-situ observation and mechanism of calcium–magnesium–alumina–silicate (CMAS) melts-induced degradation of RE2SiO5 (RE = Tb, Dy, Ho, Y, Er, Tm, and Yb) ceramics at 1500 °C

In-situ observation and mechanism of calcium–magnesium–alumina–silicate (CMAS) melts-induced degradation of RE2SiO5 (RE = Tb, Dy, Ho, Y, Er, Tm, and Yb) ceramics at 1500 °C

Rare earth (RE) silicate is one of the most promising environmental barrier coatings for silicon-based ceramics in gas turbine engines. However, calcium–magnesium–alumina–silicate (CMAS) corrosion becomes much more serious and is the critical challenge for RE silicate with the increasing operating t...
