摘要：
Five mixed corrosion media with varying CMAS/NaVO₃ ratios (CxV10-x, where x denotes the mass percentage of CMAS) were designed in this study and coupled corrosion tests were conducted on Gd₂(Hf₀.₇Ce₀.₃)₂O₇ (GH7C3) ceramic bulks at 1200 °C and 1400 °C. The results indicated that the incorporation of NaVO₃ influences on the self-crystallization behavior of CMAS. Its depolymerization effect enhances the fluidity of CMAS, thereby accelerating the corrosion process of GH7C3 ceramics by the CxV10-x mixed media. Regarding corrosion products...
