Abstract

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.
