| 摘 要： | 采用溶胶凝胶(Sol-gel)法，经涂刷、烧结、退火等工艺制备了添加不同含量SnO2的RuO2 SnO2 TiO2／Ti涂层钛阳极。并通过X射线衍射(XRD)、差热分析(DTA)、透射电镜(TEM)分析了SnO2组元对RuO2 TiO2 SnO2／Ti钛阳极涂层组织、晶粒尺寸和外观形貌的影响。结果表明：本实验所获涂层颗粒为纳米结构，且添加SnO2组元有显著细化涂层晶粒的效果：阳极涂层主要组成物相为(Ru，Sn,Ti)O2固溶体，SnO2组元含量增加、退火温度升高，该固溶体能稳定存在；添加SnO2组元的RuO2 SnO2 TiO2涂层晶粒外观呈较理想等轴状特征。 |

| Abstract: | Titanium anodes were sol-gel coated with RuO2+SnO+TiO2 containing various amounts of SnO2 by brushing, sintering and annealing. The effect of SnO2 on the microstructure; morphology and particle size of the RuO2+TiO2+SnO2/Ti coatings was examined by XRD, DTA and TEM. It was concluded that the crystal size of the coatings, which was on the scale of nanometers, was sharply reduced with increasing SnO2 content. At same time, it was shown that the coatings, which consisted mainly of a solid solution- (Ru,Sn,Ti)O2 , would remain stable and monophase during increases of the SnO2 content and the annealing temperature. The morphology of the RuO2+TiO2+SnO2 crystals in the coating was equiaxial, due largely to the presence of the SnO2. |
