热障涂层材料研究进展

Research Progresses in Materials for Thermal Barrier Coatings

简要概述了热障涂层材料的基本要求,介绍了国内外热障涂层材料近年来的研究状况和发展趋势。目前广泛使用的是YO稳定ZrO热障陶瓷材料及其粘结层材料,而稀土锆酸盐和稀土氧化物是非常有前景的隔热材料。

Thermal barrier coatings（TBCs）offer the potential to significantly improve efficiencies of aero engines as well as gas turbine engines for power generation. State-of-the-art TBCs,typically consisting of an yttria-stabilized zirconia top coat and a metallic bond coat, have been widely used to prolong lifetime nowadays. In the paper, research status and progresses of materials for thermal barrier coatings are briefly reviewed. Except yttria stabilized zirconia,other materials such as lanthanum zirconate and rare earth oxides are also promising materials for thermal barrier coatings.
