中文摘要：

涂层-基体体系作为高温热障防护结构被广泛应用于航空、航天、核反应堆等涡轮发动机叶片上，主要作用是抵抗高温燃气，保护基体材料．在服役过程中，涂层过早出现开裂、脱粘等失效行为直接影响发动机的安全性和可靠性．长期以来，热障涂层力学性能的实验测试方法是国内外研究者关注的重点．首先分析了导致热障涂层失效的失配应力的来源，重点介绍了热障涂层力学性能研究的实验测试方法、仪器和针对界面脱粘检测的红外热像技术，接着概述了热障涂层寿命预测方法，最后分析当前研究中存在的问题，并对未来的发展的一些方向和有待于进一步研究的问题作了总结．

英文摘要：

Thermal barrier coatings （TBCs） are widely used in turbine blades of aeronautics, astronautics and nuclear reactors for the purpose of insulation from hot gas stream and protection of metallic substrate. However, the gas-turbine engines are under the threat of premature TBCs failures, such as fracture and spallation during service. The experimental measurement methods of mechanical properties of TBCs have become the major tasks. The research progresses of TBCs are reviewed, including the origins of misfit stresses leading to TBCs failure, the experimental measurement methods and systems on mechanical properties of TBCs, the thermography technique for the non-destructive detecting of interracial spallation of TBCs, the life prediction of TBCs and the shortages in the current researches as well as future development of TBCs.
