摘要
Electroreduction of Co(Ⅱ) to metallic Co in acetamide-urea-NaBr melt at 353 K is irreversible in one step. Gd(Ⅲ) is not reduced to Gd alone, but can be inductively codeposited with Co(Ⅱ). The amorphous Gd-Co alloy films were obtained by potentiostatic electrolysis. With the cathode potential shifting to negative direction, the content of gadolinium in the alloy increases and can get to 65.89% (mass fraction). The additive of Na 2EDTA can make the diameter of the particles of crystalline alloy smaller and change the shape of particles.
