摘 要：<正> The cyclic voltammetry and potentiostatic electrolysis were used to investigate the preparing of Dy-Bi alloy films in LiCl-DMSO （dimethylsulfoxide） system. The effects of several factors including the potential of deposition, concentrations of main salts, and the concentration ratio of DyCl3 to Bi（NO3）3 were studied. Dy-Bi alloy films containing 4.82%-80.62% （mass fraction） dysprosium were prepared in DyCl3-Bi（NO3）3-LiCl-DMSO system by controlling the system composition and deposition conditions. The films are gray, unifonn, metallic luster and adhere firmly to the copper substrates analyzed by SEM （scanning electron microscope）, EDS （X-ray energy dispersive analysis）, and XRD （X-ray diffraction）. After heat treatment at 718 K for 1 h, the alloy phase of Dy-Bi was found in XRD patterns.
