The electrodeposition behavior of cobalt in a urea-acetamide-LiBr melt was investigated using a tungsten electrode at 353 K. Cyclic voltammetry studies demonstrated that the reduction of Co(II) to Co is an irreversible, one-step, two-electron transfer process, and chronoamperometry experiments revealed that the electrodeposition of cobalt proceeds via 3D instantaneous nucleation with diffusion-controlled growth on the tungsten electrode. The electrodeposition of cobalt was performed at various cathodic potentials (−0.75 to −0.90 V) and temperatures (343 to 373 K) in a urea-acetamide-LiBr melt. The deposits were examined using scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), and X-ray diffraction (XRD). The SEM images revealed that uniform, dense, and compact deposits were obtained at more positive cathodic potentials between 343 and 353 K. The EDS and XRD analysis confirmed that the obtained deposits were pure cobalt.
