Abstract:Cyclic electrodeposition was used to investigate the preparation of Er-Co-Bi alloy thin film in DMSO system. Experimental results indicate that Er-Co-Bi alloy thin film containing 14.83 % 32.65 % Er is prepared from 0.1 mol/L ErCl3+0.1 mol/L CoCl2+0.1 mol/L Bi(NO3)3+0.1 mol/L LiCl +DMSO system by cyclic electrodeposition on Cu substrate. The optimum cyclic potential of electrodeposition is that upper potential is within a potential range from-0.50V to -1.00 V and lower potential is within a potential range from -2.00 V to -2.60 V. The surface of alloy thin film observed by scanning electron microscope is black, adhesive and has metallic luster. The film is amorphous proved by the X-ray diffractometry.
Key words: Er-Co-Bi thin film; rare earth; cyclic electrodeposition; dimethylsulfoxide
