摘要
采用循环伏安曲线、电子探针、X射线衍射法,研究了尿素-NaCl-NaAc-CoCl2-LaCl3熔体中镧钴电解共沉积。阴极电位、电流密度、熔体中La3+/Co2+摩尔比以及电极基体均影响沉积物中的含镧量。沉积物由Co和La组成,两者并未形成金属间化合物。
The cyclic voltammetry, electron probe and X-ray diffraction analysis were used to study the electrolytic codeposition of lanthanum cobalt in urea-NaCl-NaAc-CoCl_2-LaCl_3 melt. The influences of cathodic potential, current density, La ̄(3+) La ̄(3+)/Co ̄(2+) molar ratio in the melt and the electrode substrates on the contents of La-Co deposits have been investigated. The deposit consists of Co and Lawhich do not form the intermetallic compound.
