Effect of Molten-Salt Chemistry on Phase Evolution and Corrosion Degradation of Sc2O3-Y2O3 Co-Stabilized ZrO2 Thermal Barrier Ceramics
The corrosion resistance of electron-beam physical vapor-deposited (EB-PVD) zirconia thermal-barrier coatings depends on ceramic phase stability. Here, conventional 8YSZ and two Sc2O3-Y2O3 co-stabilized ZrO2 coatings, ScYSZ and ScYSZ with an Al-rich interlayer (ScYSZA), were comparatively investigated under three chlor...
