The influence of the cationic composition on the electrochemical deposition of zinc on plane cathodes was investigated. Electrochemical deposition of zinc from aqueous feed needs high purity of the feed electrolyte owing to sensitivity of the hydrogen overvoltage. In contrast to sulfate-based electr

β¦ Synopsis
The magnetic field effect on the morphology of electrodeposited zinc was investigated in a thin-layer ZnSO4 aqueous solution. The growth morphology drastically changed from DLA-like and dendritic patterns in 0T to a spiral pattern and an asymmetric dendrite in magnetic fields lower than 0.5 T, respectively, and both patterns changed into a dense and compact one in magnetic fields higher than 1 T.
