Abstract

It is difficult to obtain a single-phase environmental barrier coating material that simultaneously offers the advantages of low thermal conductivity, a suitable coefficient of thermal expansion, and excellent corrosion resistance. Herein, to synthesize the advantages of single-phase materials, we have developed an effective approach for the design of high-entropy multiphase ceramics of rare earth oxides and silicates. Such a specific design approach is capable of making high-entropy RE2SiO5/RE2O3 and RE2SiO5/RE2Si2O7 (RE = Lu, Yb, Tm, Er, Ho, and Y) multiphase ceramics as two types of potential environmental barrier coating materials for Al2O3f/Al2O3 and SiCf/SiC ceramic matrix composites.

通过高熵多相设计提高环境阻隔涂层材料综合性能的研究

要获得一种同时具有低热导率、合适的热膨胀系数和优异的耐腐蚀性等优点的单相环境屏障涂层材料十分困难。在此，为了综合单相材料的优势，我们开发了一种设计稀土氧化物和硅酸盐高熵多相陶瓷的有效方法。这种特定的设计方法能够制造出高熵 RE2SiO5/RE2O3 和 RE2SiO5/RE2Si2O7 （RE = Lu、Yb、Tm、Er、Ho 和 Y）多相陶瓷，作为 Al2O3f/Al2O3 和 SiCf/SiC 陶瓷基复合材料的两种潜在环境屏障涂层材料。

期刊介绍： npj Materials Degradation considers basic and applied research that explores all aspects of the degradation of metallic and non-metallic materials. The journal broadly defines ‘materials degradation’ as a reduction in the ability of a material to perform its task in-service as a result of environmental exposure. The journal covers a broad range of topics including but not limited to: -Degradation of metals, glasses, minerals, polymers, ceramics, cements and composites in natural and engineered environments, as a result of various stimuli -Computational and experimental studies of degradation mechanisms and kinetics -Characterization of degradation by traditional and emerging techniques -New approaches and technologies for enhancing resistance to degradation -Inspection and monitoring techniques for materials in-service, such as sensing technologies
