| 摘 要： | 激光对含Ａｉ、Ｔｉ、ＴｉＯ２等涂热障涂层进行了重熔处理。与不含Ａｌ、Ｔｉ、ＴｉＯ２激光重熔Ｚｒ２涂层相比，一广大晶粒得到 ，另一方面由原来的柱状结构变为胞状结构。能谱分析表明，Ａｌ、Ｔｉ在胞晶之间发生了偏析。讨论了添加剂成分的作用机理。 |

| Abstract: | Plasma sprayed TBCs with Al,Ti and TiO 2 was remelted by laser.Much finer grain of ZrO 2 was obtained and cellular microstructure but not columnar microstructure which is the characteristic of laser remelting ZrO 2 without additive was also obtained.EDAX results showed that Al,Ti were segregated in the grain boundary.The effect of the additive on the microstructure was evaluated. |
| Keywords: | laser remelting thermal barrier coatings cellular microstructure |
