Abstract

Experiments have been carried out on the deposition of zinc by constant and pulsating overpotential from alkaline zincate solutions. In pulsating overpotential deposition the amplitude values of overpotential used were smaller than the critical overpotential for dendritic growth. The transformation of the form of the zinc deposit from spongy to dendritic in constant overpotential electrodeposition is shown. The possibility of obtaining smooth deposits in pulsating overpotential electrodeposition is also shown.
