摘要
用X射线衍射(XRD)对比分析实验镍渣和工厂镍渣的成分,采用恒电位扫描法测定了电解镍在电镀液中的钝化曲线,研究了氯离子浓度对镍阳极溶解行为的影响,并用扫描电镜观察了电镀后镍阳极表面的残渣形貌,探讨了镍残渣形成机理。
The composition was contrasted and analyzed using X - ray diffraction （XRD） for the nickel slag of experiment and factory. The passivation curve of the nickel was measured by the constant potential scanning in plating solution, the influence of the chloride ion concentration on the dissolution behavior of the nickel anode was studied, and the microstructure of slag at plated nickel was investigated by the scanning electron microscope. The passivation mechanism of nickel slag was discussed
