| 摘 要： | 为充分发掘氧化锆(YSZ:ZrO2-6wt%Y2O3)基热障涂层的潜力,利用纳米级的YSZ粉末作为陶瓷涂层原材料,分别对采用等离子喷涂(APS)和电子束物理气相沉积(EB-PVD)沉积具有纳米结构陶瓷涂层的工艺过程进行全面研究.对比性试验结果表明,涂层中引入纳米结构使热障涂层具有更高的隔热效果,更高的硬度以及更高的抗剥落能力.并对纳米结构陶瓷涂层微观结构的高温稳定性进行研究分析. |

| Abstract: | To exploit full potentials of the current widely used yttria-partially-stabilized zirconia(YSZ),nano-sized YSZ powders were developed and used as the ceramic source material.By controlling the deposition processes,novel TBCs with outstanding nanostructures such as nano-sized grains and pores were produced by atmospheric plasma spray(APS) and electron beam physical vapor deposition(EB-PVD),respectively.The incorporated nanostructures in TBCs resulted in substantial increase in hardness,thermal barrier effect and lifetime against thermal cycling.The long-term microstructural stability of nano-coating at elevated temperature was also evaluated. |
| Keywords: | TBCs EB-PVD APS nanopowder nanostructure |
