| 摘 要： | 用MOD法制备CeO2纳米涂层薄膜,研究和分析了CeO2薄膜的成相重复性和表面重复性,得出了1 000℃为最佳烧结温度、烧结气氛中氧元素的摩尔百分含量为0.01%的条件;研究了不同烧结工艺对CeO2薄膜表面形貌的影响,发现随着烧结温度的提高和时间的延长,薄膜的晶粒增大,表面起伏增大,表面粗糙度也随之增大,60 min为最佳保温时间;前驱溶液的浓度也会影响薄膜的致密性,浓度过大会使薄膜出现孔洞。

| Abstract: | The nano-coating CeO2 films were deposited on Ni substrates by MOD method.The deposition phase and surface-phase reproducibility of film were researched.The optimized annealing temperature for CeO2 growth is 1 000 °C and the 0.01% mol Oxygen content is better condition.By the investigation of the film flatness at different deposition processes,it was found that the grain size is increased when the annealing temperature and time increase,60 min is suitable.The concentration of the precursor solution also influences the quality of the CeO2 film.It will have more holes when the precursor solution concentration becomes thicker. |
