Stripping Voltammetry of Zn-Ni-Cu Alloy Nanoscale Films

The voltammograms of ZnNiCu alloy films dissolution are presented in comparison with the voltammograms of CuNi, CuZn, ZnNi binary alloys dissolution. The films were obtained in a potentiostatic mode in ammonia-glycinate electrolytes and were anodically dissolved in alkaline ammonia-glycinate and sodium sulfate solutions. It was revealed that the ternary alloy film is multiphase and includes the α and ε-phases of the CuZn alloy, the γ- and β-phases of the ZnNi alloy, as well as the phase of pure Cu.
