Surfaces of alloy films obtained by these two techniques are smooth, adhesive, compact and metallic luster. The contents of La in alloy films obtained by potentiostatic electrolysis technique are in the range of 13.23%～47.67%. The contents of La in alloy films deposited by pulse electrolysis technique are in the range of 10.67%～16.29%.展开更多

Cyclic voltammetry indicated that the reduction process of Nd(III) on the Pt cathode was complicated. The one-step reduction wave showed two steps by adding 0.3 mol/L ethylenediamine(EN). A delicate yellow, lustrous, strongly adhering film on the Cu electrode was obtained using potentiostatic electrolysis at -1.80 V (vs. aq SCE).展开更多
