摘要

本文综述了作者在非氧化物陶瓷环境屏障涂层(EBC)方面的研究进展，并对近年来的研究成果进行了讨论。综述了近年来共晶涂层的研究进展。作者开发了用于掺lu2o3氮化硅陶瓷的EBC。由于初步的材料筛选试验表明，Lu2Si2O7相具有优异的抗水蒸气腐蚀性能，因此主要在该相的基础上进行了EBC的开发。本文综述了一些氧化物在静态和动态蒸汽喷射水蒸气环境中的衰退行为，以及含EBC的氮化硅陶瓷的蒸汽喷射试验，以及含氧化物共晶结构的EBC的制备。这里描述了作者工作的一个例子，因为它可以制造无裂纹的Al2O3-HfO2共晶涂层。

Development of environmental barrier coatings for non-oxide ceramics

ABSTRACT This review article outlines the authors’ previous works on environmental barrier coatings (EBC) for non-oxide ceramics and discusses what has been revealed since then. It also provides an overview of the research on eutectic coatings as EBC's that has been carried out in recent years. The authors have developed EBC for Lu2O3-doped silicon nitride ceramics. Since preliminary material screening tests revealed that Lu2Si2O7 phase has superior resistance against water vapour corrosion, the development was carried out mainly on EBC's based on this phase. This review addresses recession behaviours in static state and dynamic steam jet water vapour environments for some oxides, as well as under steam jet test for silicon nitride ceramics with EBC's, in addition to fabrication of EBC's with oxides eutectic structure. One example of the authors’ works is described here, since it can fabricate a crack-free Al2O3–HfO2 eutectic coating.
