The cyclic voltammetry, potentiostatic electrolysis and open circuit potential-time curve after electrolysis, current-time curve at potential step, X-ray diffraction, EDAX and electron probe microanalysis were used to investigate the electrodeposition of rare earth metals and their alloys in molten chlorides. The electrode processes and the mechanism of forming alloy were studied. The free energies of formation for the intermetallic compounds, the diffusion coefficients and diffusion activation energies of RE(III) ions in melt, the diffusion coefficients and diffusion activation energies of RE atoms in alloy phase were determined. The rare earth-iron group alloys were prepared by consumable cathode and electrolytic codeposition. 展开更多
