“…This anomalous process is reported by many works in the literature 4,[6][7][8][9] and various explanations of the anomaly have been suggested, e.g. underpotential codeposition (UPD), kinetic behavior, the hydroxide suppression mechanism, and the influence of Co (III) 10 . However, it is always considered that certain experimental conditions, such as high values of current density (I), for example, can change the process from anomalous to normal and under these conditions the ZnCo alloy coatings presented a cobalt content higher than that of zinc 11,12 .…”
