摘 要: 利用循环伏安法和恒电位电解法研究了室温下在二甲基亚砜溶剂(DMSO)中Y-Ni功能合金膜的电沉积制备。 结果表明， 在YCl3 (0.10 mol·L-1)NiCl2 (0.10 mol·L-1)DMSO溶液中， 控制电位在-1.15～-2.50V范围内进行恒电位电解， 可得到有金属光泽、 附着力强的银灰色非晶态Y-Ni合金膜，厚度约为1.4μm。 Y-Ni合金膜中Y的含量在3.5%～80%范围内随阴极电位的负移而增加。

Abstract:The electrodeposition of Y-Ni alloy film from dimethylsulfoxide (DMSO) electrolyte solution was investigated using cyclic voltammetry and potentiostatic technique. The cyclic voltammograms of Pt and Cu electrodes in YCl3 (0.10 mol·L-1)NiCl2 (0.10mol·L-1)DMSO were measured， which indicate that the Y-Ni alloy can be electrodeposited. The Y-Ni film on Cu electrode was obtained by potentiostatic electrolysis at -1.15～-2.50 V (vs SCE). The Y-Ni film is amorphous， Y content is in the range of 3.5%～80% and thickness is about 1.4μm analyzed by EDAX and XRD. The Y content in deposited film increases with the shift of cathode potential to negative direction.
