Hypothesis
Can a high-entropy strategy enhance the corrosion resistance of rare earth zirconates against CMAS?
Conclusion
The high-entropy strategy significantly improves the corrosion resistance of rare earth zirconates against CMAS.
Supporting Evidence
- Rare earth elements impede element diffusion and hinder CMAS infiltration.
- Larger ionic radii of rare earth elements enhance solubility in apatite.
- The high-entropy strategy effectively improves corrosion resistance.
Takeaway
This study shows that mixing different rare earth elements can make materials better at resisting damage from high-temperature melts.
Methodology
The study synthesized high-entropy rare earth zirconates and tested their corrosion behavior against CMAS at high temperatures.
