| 英文摘要 | In this work, the water vapor corrosion behaviors of plasma sprayed ytterbium silicate coatings with different contents of Yb2O3, Yb2SiO5 and Yb2Si2O7 phases were evaluated at 1400 degrees C for 100-300 h and the influence of phase compositions on the corrosion behaviors was analyzed. The results showed that severe corrosion took place in the Yb2Si2O7-rich coating with a porous reacted layer with a thickness about 20 mu m after 300 h corrosion. The Yb2O3 phase in the Yb2O3-rich coatings volatilized, lefting a relatively dense reacted layer with a thickness about 5-6 mu m after the same corrosion time. A layer composed of Yb2SiO5 was formed on the surface of all the corroded ytterbium silicate coatings. This study may provide theoretical basis for selecting rare-earth silicate environmental barrier coatings (EBCs) with excellent performance. |
