Electrodeposition of Pr-Fe alloy films in urea-dimethylsulfoxide

摘要

Cyclic voltammetry and chronoamperometry were used to investigate the electrochemical behavior of Pr^3+ ions in a system of 0.01 mol-dm-3 Pr(CH3SO3)3 + 0.01 mol-dm^-3 FeCl2+ 3.0 mol.dm^-3 urea + DMSO on a Pt electrode. Some electrochemical parameters were measured. Potentiostatic depositions between -1.6 and -2.4 V were applied to deposit Pr-Fe films in urea-DMSO mixed solution. The Pr content in the alloy films was in the range of 34.89 wt.% to 37.15 wt.%.The Pr-Fe alloy films are proven to be amorphous by XRD (X-ray diffraction).
