电化学方法制备铜钴纳米多层膜

Electrodeposition of Cu-Co Multilayer Thin Films

采用旋转圆盘电极、双脉冲电位法从单一的含有铜离子和钴离子的镀液中电沉积Ｃｕ－Ｃｏ纳米多层膜、并用ＴＥＭ．ＡＥＳ和Ｘ－射线衍射研究镀层的形貌和组成。结果表明：多层膜结构为纯铜和含有少量铜的铜钴合金层交替组成，铜在钴层中的含量，随镀液中的铜含量的增大和转速的提高而提高。

A method has been developed to produce Cu-Co Multilayer from a single electrolyte by electredeposition. The effects of the concentration of copper ions,current density and the speed of rotation were investigated,and the Cu-Co electrodeposition films were analysed by TEM. AES and X-ray diffraction.The results indicated that the film was alternating pure copper and coppercobalt alloy layers. If the content of copper in cobalt layer is to be small,the concentration of its ions in solution must be small and the rotation speed must be low.
