摘要：
In the process of industrial electrodeposition of nickel, the grain size of the nickel will directly affect its application in industrial production. Therefore, refinement of deposited layer grains is particularly important. In this paper, a three-electrode system was selected to investigate the influence of cerium(Ⅳ) sulfate on the electrocrystallization behavior of electrodeposited nickel by testing the cathodic polarization curve, cyclic voltammetry curve and timing current curve at different (0-1.5 g/L) cerium(Ⅳ) sulfate concentrations in industrial electrolytes. The grain size and structure orientation of nickel deposited layer were analyzed by SEM and XRD, and the effect of cerium (Ⅳ) sulfate on grain refinement and crystal growth orientation of nickel deposited layer in industrial electrolysis was investigated. The results show that the initial deposition potential of nickel is negatively shifted and the cathodic over potential increases after the addition of cerium(Ⅳ) sulfate, and the addition of cerium (Ⅳ) sulfate promots the electrocrystallization of nickel. When cerium(Ⅳ) sulfate is not added, the deposited layer has coarse and uneven grains. The nickel deposited layer grains are significantly refined with the addition of additives. When the addition concentration is 0.6 g/L, the peak current is the largest and the nucleation relaxation time is the shortest, the grain size of the deposited layer is the smallest and the refinement effect is the best, which is the optimal addition concentration of cerium(Ⅳ) sulfate. © 2023 Central South University of Technology.
