摘要
考察了YSZ热障涂层的抗热循环性能;分别利用SEM、XRD分析了热循环前后涂层的显微结构和相组成。经分析可知,YSZ热障涂层具有典型的柱状晶结构,沉积态时YSZ涂层为t/t′相,经过600次热循环后,YSZ涂层未发现脱落。
The thermal cycle characteristics of yttrium stabilized zirconia（YSZ） thermal barrier coatings（TBCs） was studied.The microstructure and phase composition of YSZ coatings before and after thermal cycle were analysed respectively by SEM and XRD.The analysis show that YSZ coating is the representative morphology for the EB-PVD coatings..The phase composition of YSZ coatings is the t/t′ phases on the depositon stae.and the spallation is not observed after 600 thermal cycles.
