Abstract

High-temperature CMAS corrosion has become a crucial factor inhibiting the further development of thermal barrier coatings (TBCs) because of the increasing service temperature of aero-engines. Herein, a novel mid-entropy rare-earth hafnate (YGdYb)HfO (YGYbH) was prepared by ultrafast high-temperature sintering (UHS) technology, and its CMAS corrosion behavior and mechanism were investigated. During corrosion, the CaRE(SiO)O apatite phase with a lower formation enthalpy and entropy-stabilized effect had a more intense tendency to be generated, which improves the density and stability of the reaction layer, hindering the further penetration of molten CMAS. Moreover, the significant lattice distortion caused by the rare-earth ions with different radii impeded the ionic diffusion, which delayed the CMAS corrosion reaction. In general, YGYbH, with excellent CMAS corrosion resistance, has the potential to serve as a next-generation TBC material.

摘要

由于航空发动机服役温度不断提高，高温CMAS腐蚀已成为阻碍热障涂层（TBCs）进一步发展的关键因素。在此，采用超快高温烧结（UHS）技术制备了一种新型中熵稀土铪酸盐（YGdYb）HfO（YGYbH），并对其CMAS腐蚀行为及机理进行了研究。在腐蚀过程中，具有较低生成焓和熵稳定效应的CaRE(SiO)O磷灰石相有更强烈的生成倾向，这提高了反应层的密度和稳定性，阻碍了熔融CMAS的进一步渗透。此外，不同半径的稀土离子引起的显著晶格畸变阻碍了离子扩散，从而延缓了CMAS腐蚀反应。总体而言，具有优异CMAS耐蚀性的YGYbH有潜力作为下一代TBC材料。
