在氯化物电解液中以定电量 (10C cm- 2 ) ,恒温 4 0℃电沉积Zn Fe族元素二元合金 .沉积产物用原子吸收光谱分析 .根据分析结果 ,作出相应的电流效率、百分含量及部分极化曲线 .镀层形貌采用扫描电镜 (SEM)观察 ,发现 :Zn Fe族元素合金的共沉积为异常共沉积 .Cl- 对铁族元素有催化作用 .随着Cl- 浓度的增加 ,降低了铁族元素的过电位 ,促进了铁族元素金属的沉积 .
In the chloride electrolyte in the constant power (10C cm-2), constant temperature 40 ℃ electrodeposited ZnFe binary element alloy deposition products by atomic absorption spectroscopy analysis based on the results to make the corresponding current efficiency, percentage Content and partial polarization curve.The morphology of the coating was observed by scanning electron microscopy (SEM) and found that the co-deposition of Zn-Fe-based alloy was abnormal co-deposition.Cl- had a catalytic effect on the iron group.With the increase of Cl- concentration , Reducing the overpotential of iron group elements and promoting the deposition of iron group metal elements.
