Electroreductions of Co(Ⅱ) and Ni(Ⅱ) to metallic Co and Ni in urea-NaBr melt at 393K are irreversible respectively in one step.La(Ⅲ) does not be reduced to La alone,but can be inductively codeposited with Co(Ⅱ) or Ni(Ⅱ).The amorphous La-Co and La-Ni alloy films were obtained by potentiostatic electrolysis.To some extent,the contents of La in La-Co and La-Ni deposits increase with the cathode potential shift to the negative direction.
