Abstract

High-temperature water vapor corrosion is a great challenge for long lifetime of Si/mullite/Yb₂SiO₅ Environmental Barrier Coatings. In this work, the Yb₃Al₅O₁₂ modified layer was in-situ synthesized on the surface of Yb₂SiO₅ layer to improve the steam resistance. The reaction mechanism of the Al-modified layer was explored. The steam corrosion experimental results indicated that the defects in Yb₂SiO₅ layer healed, and the oxidation rate of Si-bonded coating was slowed down under the protection of modified layer. Additionally, the calculation results of first-principle molecular dynamics confirmed that Yb₃Al₅O₁₂ has excellent steam corrosion resistance.
