Cyclic voltammetry and potentiostatic electrolysis were used to investigate the preparation of Co-Bi alloy films in a LiClO 4-DMSO system. The experimental results indicate that the Co-Bi alloy films containing 14 35%-29 77% Co can be prepared via potentionstatic electrolysis on Cu substrates, at deposition potential -1 10--1 65 V( vs. SCE) and by controlling the system composition and deposition condition. They are uniform gray films with a metallic luster and they are adhered firmly to the Cu substrate. The films were analyzed by EDS, SEM and XRD. After heat treatment of crystallization at 275 ℃ for 1 h, the alloy phase of Co-Bi can be confirmed via the XRD pattern.
