Assessment criteria for the corrosion resistance of Gd2Zr2O7-based thermal barrier coatings exposed to CMAS and CMAS + sea salt

npj Materials Degradation
Gd2Zr2O7 (GZO) thermal barrier coating is famous for its excellent resistance to CaO-MgO-Al2O3-SiO2 (CMAS) corrosion, and the judgment is that molten CMAS infiltration can be suppressed by its rapid reaction with GZO, but the judgment criteria are lack ...

Crystallization behavior of calcium–magnesium–alumina–silicate coupled with NaCl/Na2SO4

Corrosion Communications, 2023
Promoting molten calcium–magnesium–alumina–silicate (CMAS) crystallization can highly reduce the melt penetration into thermal barrier coatings (TBCs), which alleviates its corrosion to TBCs. In marine environments, many salts are coupled with CMAS.
