| 英文摘要 | High thrust-to-weight ratios and high propulsion are necessary requirements for revolutionizing the aviation technology. Emerging hot-section engine components are currently focused on SiCf/ SiC ceramic matrix composite materials, wherein the environmental barrier coatings (EBCs) are needed to protect the engine components from the harsh combustion environment. Due to their matched thermal expansion coefficient and good chemical compatibility with the SiC f/SiC ceramic matrix composites substrates, rare earth (RE) silicates have been identified as promising EBC materials. However, they cannot provide reliable protection for the engine components when the working temperature rises over 1300 degrees C, mainly because of their poor resistance to the low melting point oxides CaO-MgO-Al2O3-SiO2 (CMAS) melts. This review discusses the current state of research on the CMAS corrosion resistance of RE silicates. First, the interaction and degradation mechanisms of single-RE-component RE2SiO5 and RE2Si2O7 are discussed, and the different roles of RE species in reacting with CMAS melts are summarized. Then, the concept of high-entropy design is introduced, enabling synergistic optimization of the effects of multiple RE species in terms of CMAS resistance, by delicately designing the multi-RE-component (nRE(x)) compositions. Such a strategy leads to enhanced CMAS corrosion resistance in some novel (nRE(x))(2)SiO5 and (nRE(x))(2)Si2O7 materials. Finally, potential prospects, opportunities, and challenges for high-entropy RE silicates as EBC materials are discussed |
