Corrosion of Gd2O3-Yb2O3-Y2O3 co-doped ZrO2 by different types of CMAS

Key Points

• Corrosion was notably influenced by different CMAS types, affecting material integrity.
• Gd2O3-Yb2O3-Y2O3 co-doping resulted in better chemical stability against CMAS exposure.
• Assessment using laboratory tests confirmed the effects on zirconia's physical properties over time.
• Findings suggest the need for improved formulations to enhance resistance to corrosive environments.
