Effect of parameters of pulse electrolysis on concentration changes in the loose zinc deposit and deposit properties

详细

The parameters of pulse current modes (durations of pulses and pauses between pulses) have a significant influence on the growth dynamics and properties of loose zinc deposits if the process takes place under unsteady-state diffusion conditions. The coefficient k defined as the ratio of the growth time of the loose deposit to the transition time in the pulse was proposed as a criterion for describing the concentration changes. By varying the parameters of pulse electrolysis, one can change the density in situ and the morphology of the electro-deposited metal from highly porous loose deposits with branched dendritic particles to compact deposits.
