摘要: 利用CO₂、P与ZrH₂反应生成约3～5μm厚的薄膜,用扫描电镜对薄膜横截面进行形貌观察;用X光电子能谱和X射线衍射对反应层表面进行分析。分析结果证明,所得到的氢化锆表面反应层致密,与基体结合良好,具有阻挡氢的能力;反应层中含有Zr、C、O等元素;除baddeleyite结构的ZrO₂以外,还有具有C-H键和O-H键的物质。

Abstract: A film with a thickness of 3～5μm was formed by the reaction of CO₂ and zirconium hydride. Observation of the crosssection of the film by SEM found that the surface was combined tightly with the zirconium hydride. The film could be a hydrogen permeation barrier. XPS analysis showed that there were Zr, C and O in the film. Besides the ZrO₂ baddeleyite, some O-H and C-H chemical bonding also existed in the film.
