The cyclic voltammetry and potentiostatic electrolysis were used to investigate the preparation of Er-Ni-Co alloy films in LiClO4-DMSO system. Experimental results indicate that Er-Ni-Co alloy films containing Er from 9.21％ to 18.90％ were prepared from 0.1 mol•L－1 ErCl3-0.1 mol•L－1 NiCl2- 0.1 mol•L－1 CoCl2-0.1 mol•L－1LiClO4-DMSO system by potentiostatic electrolysis on Cu substrates at deposition potential from －2.20～－2.50 V (vs SCE). Their surfaces are black, uniform, adhesive, and have metallic luster.
