| 摘 要： | 采用大气等离子喷涂（APS）工艺制备了纳米氧化钇部分稳定的氧化锆（Y-PSZ）基高温封严涂层,对涂层的元素分布、孔隙率及孔隙分布等微观结构特征进行了研究,探讨了高分子聚合物（高聚物）的造孔机理。结果表明：涂层的成分均匀,纳米Y-PSZ对h-BN具有良好的包覆效果,在高聚物烧蚀后的涂层中留下均匀分布的孔隙,涂层的孔隙率可达33.0%。

| Abstract: | The nano yttria partially stabilized zirconia(Y-PSZ) based seal coating was prepared by air plasma spraying(APS) process.The microstructures including element distribution and porosity of seal coating were analyzed.In particular,the pore-forming mechanism of polymer was studied.Experimental results reveale that the composition of coating distributes evenly,the h-BN is fine embodied by nano Y-PSZ,uniformly distributed pores are left after polymer burn out,and the porosity can be up to 33.0%. |
