Microstructural change and thermal shock performance of metal / ceramic graded thermal barrier coatings in thermal shock experiments were studied by scanning electron microscope and energy-dispersive spectrometry . the results showed : 1 ) metal microstructure kept intact while ceramic microstructure had been destroyed; 2 ) thermal shock performance of coatings was interrelated with its function to relax residual stresses, therefore thermal shock performance of gradient thermal barrier coatings was better than that of terraced thermal barrier coatings; 3 ) thermal shock performance was concerned with metal content in metal / ceramic thermal barrier coatings, which would be improved when metal content was increased 利用扫描电子显微镜和能谱成分分析技术研究了金属/陶瓷梯度热障涂层在热震过程中的显微组织变化及其抗热震性能.结果表明:1)金属显微组织保持完好,陶瓷显微组织有明显的破坏;2)涂层抗热震性能与其热应力缓和功能密切相关,梯度热障涂层比阶梯热障涂层具有更高的抗热震性能;3)金属/陶瓷热障涂层抗热震性能与其中金属相含量有关,金属相含量增加可改善涂层抗热震性能
