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.展开更多

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.展开更多
