Abstract:The optimum operating conditions for the electrodeposition of nickel from all-nickel chloride electrolytes were studied, based on measurements of conductivity, surface tension, viscosity of nickel chloride electrolytes at different temperatures and concentrations of nickel chloride as well as the experiments of electrodeposition arranged using experimental design in the normal table. Through studying cathode polarization and examination of physical features of cathodic nickel, the effects of trace Fe, Co, Pb.. TBP and N-235 in all-nickel chloride electrolyte on cathode potentials, cell voltages, current efficiency and energy consumption as well as the morphology and the internal stress of cathodic nickel in electrodeposition of nickel were examined.
