The increasing demand for more efficient and environmental-friendly gas turbines has driven the development of new strategies for material development. SiC/SiC ceramic matrix composites (CMCs) can fulfil the stringent requirements; however, they require protection from the operating environment and debris ingested during operation. Environmental barrier coatings (EBCs) are a protective measure to enable the CMCs to operate under harsh conditions. EBC-coated CMCs will enable an increased efficiency and reduced pollutant and CO₂ emissions. In this review, the fundamentals of SiC/SiC ceramic matrix composites degradation in steam environments and under the presence of corrosive species, namely CaO-MgO-Al₂O₃-SiO₂ (CMAS), are first presented. Then, a summary of EBCs along with a comprehensive summary of the current compositions and their interactions with steam and molten corrosive species is presented. Finally, an overview of the latest research directions for the potential next generation of EBCs are outlined.

对更高效，更环保的燃气轮机的日益增长的需求推动了材料开发新战略的发展。SiC / SiC陶瓷基复合材料（CMC）可以满足严格的要求；但是，它们需要保护免受操作环境和操作期间吞入的碎屑的侵害。环境屏障涂料（EBC）是一种保护措施，可让CMC在恶劣条件下运行。使用EBC涂层的CMC可以提高效率并减少污染物和CO ₂排放。在这篇综述中，SiC / SiC陶瓷基复合材料的基本原理在蒸汽环境中以及在腐蚀性物质CaO-MgO-Al ₂ O ₃ -SiO ₂的存在下会降解。（CMAS），首先提出。然后，对EBC进行了总结，并对当前的组成以及它们与蒸汽和熔融腐蚀性物质的相互作用进行了全面总结。最后，概述了潜在的下一代EBC的最新研究方向。
