摘要/Abstract

摘要： 随着航空发动机服役温度的升高, 低熔点钙镁铝硅酸盐(CaO-MgO-AlO_1.5-SiO₂, CMAS)腐蚀成为导致热结构部件防护涂层失效的重要因素。在典型热障涂层(Thermal barrier coating, TBC)及环境障涂层(Environmental barrier coating, EBC)的CMAS腐蚀过程中, 稀土组分对反应产物的结晶以及CMAS腐蚀渗透过程具有显著影响。本研究聚焦TBC和EBC体系中广泛采用的两种稀土元素——钆和镱, 制备了一系列钆-镱氧化物((Gd_xYb_1-_x)₂O₃, x=0、0.05、0.10、0.20、0.30、0.50和1.00), 系统研究其与CMAS沉积物在1300 ℃下的反应产物, 并探讨这两种稀土元素的协同作用机理。结果表明, 钆离子有效诱导磷灰石结构产物的形成, 但熔体消耗效率较低; 镱离子促进石榴石和磷硅酸钙结构产物的形成, 但其产物结晶动力学迟滞。进一步讨论了钆和镱离子在产物中的配分特征以及残余CMAS熔体成分的变化, 提出在一定比例范围内(钆摩尔分数为5%~20%)两者之间存在协同效应。通过合理设计涂层中钆和镱元素的比例, 可以促进磷灰石结晶, 阻止熔体渗透, 同时改善石榴石和磷硅酸钙迟滞的结晶动力学, 从而加速熔体消耗。探究协同作用为TBC/EBC的抗CMAS腐蚀改性成分设计提供了理论支撑。

Abstract:

As the operating temperature of aero-engine rises, degradation of thermal barrier coatings (TBCs) and environmental barrier coatings (EBCs) on hot-section components affected mainly by infiltration of calcium-magnesium-alumina-silicate (CaO-MgO-AlO_1.5-SiO₂, CMAS) has garnered increasing attention. Rare earth constituents play an essential role in forming corrosion products and subsequent melt penetration when conventional TBCs and EBCs are attacked by CMAS deposits. This study focused on preparation of a series of gadolinium-ytterbium oxides ((Gd_xYb_1-_x)₂O₃, x=0, 0.05, 0.10, 0.20, 0.30, 0.50 and 1.00), with particular emphasis on the roles of ytterbium and gadolinium. Their reaction with CMAS deposits was systematically investigated at 1300 ℃ to explore the synergistic mechanism associated with these two rare earth elements. The results indicate that gadolinium cations can efficiently induce the crystallization of products with apatite structure which have a low melt consumption. Conversely, ytterbium cations can induce the formation of products with garnet and silicocarnotite structure which have sluggish kinetics. Furthermore, partitioning of gadolinium and ytterbium ions within corrosion products, along with variation of residual CMAS melt composition, was further analyzed. It is proposed that these two rare earth ions exhibit a synergistic effect within a certain composition range (5%-20% (in mole) of gadolinium content). The optimized ratio of gadolinium and ytterbium within coatings is anticipated to promote apatite crystallization, prevent melt penetration, and modify the sluggish crystallization kinetics of garnet and silicocarnotite, thereby significantly improving the melt consumption. This investigation on synergistic effect of gadolinium and ytterbium cations provides a theoretical support for the anti-CMAS-corrosion composition modification of TBCs/EBCs.

Key words: gadolinium-ytterbium oxide, CMAS corrosion, reactive crystallization product, synergistic effect
