“…Several factors such as zinc concentration [5], complexing agents [6], anions [7,8], and additives [9] play fundamental roles in zinc electrodeposition. These factors may modify the texture and morphology of zinc electrodeposited coatings [10][11][12][13]. Although, several works have been reported in literature, the relation between the morphology of the deposits and their electrochemical parameters are still not clear [14].…”

An electrochemical study of zinc deposition was carried out in baths containing 0.5 M ZnCl2 and 0.4 M H3BO3. From the voltammetric study it was found that, in our experimental conditions, zinc electrodeposition is quasi-reversible and occurs under charge transfer control. The average coefficient diffusion calculated was D = 7.14 × 10-6 cm2s-1 while the standard constant at electrode charge was 8.78 × 10-3 cms-1. The nucleation and growth parameters determined from the potentiostatic study showed that, at bigger overpotentials, a vertical growth is favored, suggesting a dendritic growth. The critical cluster´s size calculated was 2, indicating that each active site is formed by two zinc atoms on the glassy carbon electrode (GCE) surface, while the ΔG for the formation of stable nucleus was 1.35 × 10-20 J/nuclei. The Scanning Electron Microscopy images showed thin platelets of hexagonal crystals and dendrites at lower and higher overpotentials applied, respectively.

“…The texture of the deposit depends on the plating conditions, such as the bath chemistry, the current density, the pH of the plating bath, the additives, the orientation of the substrate grain, and the nature of the nish of the substrate surface. Tomov et al 2 investigated the evolution of texture in Zn deposits from a plating bath based on Zn chloride. The texture of the coatings depended on the inhibitors added to the bath.…”
