ErCo-Bi thin film%rare earth%cyclic electrodeposition%dimethylsulfoxide
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 -0.50 V 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.
