Erosion behavior of CMAS/VA infiltrated EB-PVD Gd2Zr2O7 TBCs: Special emphasis on the effect of mechanical properties of the reaction products

Aero-engines operating in sand-laden (CMAS/CaO–MgO–Al2O3–SiO2) environments often encounter severe problems with thermal barrier coatings (TBCs) due to CMAS infiltration and erosion damage. This study focuses on a deeper understanding of the erosion behavior of CMAS-infiltrated EB-PVD Gd2Zr2O7 TBCs. The study includes isothermal infiltration of different CMAS and subsequent erosion tests at room temperature.
