Anodic behavior of zinc, cadmium, and their alloys with barium in chloride and oxide-chloride melts

The anodic polarization of zinc, cadmium, and their alloys with barium in chloride and oxide-chloride Ba-containing electrolytes is investigated. The dissolution of barium from alloys is accompanied by the concentration polarization from the side of the metal phase and proceeds selectively. The influence of electrocapillary effects on the anodic polarization of both metal zinc and cadmium and their alloys with barium is shown. The thickness of the diffusion layer in the Ba-Zn and Ba-Cd alloys is calculated. During the polarization of zinc, cadmium, and their alloys with barium in the oxide-chloride melts, the portions appear in the curves, which correspond to the limiting rate of the diffusion mass transfer of dissolved BaO to the surface of metal anodes.
