| 摘 要： | 利用非平衡磁控溅射离子镀技术以纯钨靶和纯石墨靶作为溅射源制备了C/W纳米多层膜。采用X射线衍射（XRD）、X射线光电子能谱（XPS）和高分辨透射电子显微镜（HRTEM）对薄膜相组成及其微观组织结构进行了分析。结果表明：W含量约为9 at.%的C/W薄膜具有周期厚度约为6.5 nm的多层结构;沉积的W元素不以单质态存在,而是与碳元素反应生成了WC纳米晶;薄膜中的碳为非晶态,碳主要以sp2键类石墨态存在。

| Abstract: | The C/W multilayered films have been prepared by unbalanced magnetron sputtering ion plating using graphite target and tungsten target as sputter source.The phase composition and microstructure were analyzed by XRD,XPS and TEM.The results showed that the C/W multilayered film with～9 at.% W have a average periodicity of～6.5 nm.Investigation of TEM and XPS showed that W element is not present as metal state but WC nano-crystalline formed by reacting with C element,the SAED image showed that carbon is amorphous,the XPS analysis showed that the bonding of carbon is mainly sp2 graphite. |
