中文摘要: 随着航空航天技术的快速发展,飞行器热端部件的服役温度越来越高,YSZ热障涂层已经无法满足目前航空发动机热端部件的服役需求,稀土元素钆(Gd)与镱(Yb)对YSZ进行掺杂得到的Gd2O3-Yb2O3-Y2O3共稳定氧化锆(GYYZO)被广泛认为在超高温工况下具有广阔的应用前景。本研究采用固相反应法与化学沉淀法分别制备了两种球形GYYZO粉末,并采用大气等离子喷涂法制备了两种GYYZO陶瓷热障涂层,研究了粉末制备工艺对粉体结构以及涂层结构与性能的影响。
Abstract:With the rapid development of aerospace technology, the operating temperature of hot-end components of aircraft is becoming increasingly higher. YSZ thermal barrier coatings can no longer meet the service requirements of current aircraft engine hot-end components. Gd2O3-Yb2O3-Y2O3 co-stabilized zirconia (GYYZO), obtained by doping YSZ with rare earth elements gadolinium (Gd) and ytterbium (Yb), is widely considered to have broad application prospects in ultra-high temperature conditions. In this research, two types of spherical GYYZO powders were synthesized using the solid-state reaction and chemical precipitation methods, while two variants of GYYZO ceramic thermal barrier coatings were fabricated through the atmospheric plasma spraying technique. The effects of powder preparation process on powder structure and coating structure and properties were studied.
