Abstract
n this paper, the electrodeposition kinetics of the Mn-Bi system in a mixed sulfate nitrate bath is reported. The plating bath is characterized by the presence of some additives like the boric acid and the ammonium sulfate. In this work, cyclic voltammetry is used to characterize reduction and dissolution potential of each element. The morphological and the chemical composition of the deposit were determined by scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS). The deposit has a heterogeneous appearance with different grain size, the energy dispersive spectroscopy (EDS) analysis reveals the presence of manganese and bismuth peaks with almost the same intensities.
