摘要/Abstract

摘要：

利用大气等离子喷涂技术和纳米粉体造粒料, 制备了3mol% Y₂O₃部分稳定ZrO₂热障涂层. 利用扫描电镜(SEM)、透射电镜(TEM)研究了涂层的显微结构, 采用差示扫描量热仪(DSC)、激光脉冲法热导仪对涂层的热物理性能进行了实验研究和理论分析. 结果表明: 利用纳米粉体造粒料和等离子喷涂技术可获得导热系数为0.63~0.80W/(m·K)的热障涂层. 原因在于涂层显微结构中大量分布均匀的微小气孔和平均长度在十几微米的、垂直于热流方向的层状微裂纹. 相变可导致涂层热物性变化异常. 热处理后涂层的晶粒长大和气孔率降低可导致导热系数升高.

Abstract:

ZrO₂-3mol% Y₂O₃coating was deposited by air plasma spraying using reconstituted nanosize particles. The microstructure was examined by SEM and TEM. The thermal conductivity was calculated based on the specific heat and thermal diffusivity detected by DSC and laser flash method. The results show that the thermal barrier zirconia coating with thermal conductivity ranging from 0.63-0.80 W/(m·K) is obtained. This can be attributed to the homogeneous distribution of micro-size pores and amounts of micro-cracks with average length of about 10 μm, to which heat flow is nearly perpendicular. The phase transition of t to m can result in the change of thermophysical properties. The grain growth and the decrease of porosity lead to increase of thermal conductiviy of as-sprayed coating.
