“…It is well known that in aqueous systems there is a competition between adsorbed hydrogen and Zn ions for the active surface sites (38)(39)(40)(41). However, quaternary amines are also known to be selectively adsorbed from aqueous Zn plating solutions (42)(43)(44) and for this reason are often added as brighteners in commercial plating baths (45). Alcohols have also been used as blocking additives (46).…”

This work is an initial study of the zinc deposition process from a Lewis-basic choline chloride/ ethylene glycol deep eutectic solvent containing ZnCl 2 at 30°C. The system was examined by cyclic voltammetry at static and rotating glassy carbon disc electrodes and by potential step techniques. Although there was little deposition initially on sweeping or stepping the potential to -0.5 to -0.8 V vs. Zn/Zn(II) more rapid deposition was observed when the potential was raised to -0.4 to -0.2 V. The role of choline chloride was also examined by comparison with a choline-free electrolyte, which exhibited a more conventional voltammetric response. A tentative suggestion has been proposed to account for the observed deposition behaviour.

“…It affects the peak size by shifting Zn deposition potential to more negative values. Referring to the literature [34], ionic adsorption is modified when the electrode charge is more negative. Anions near the surface are repelled; the layer of external SDIPNS cations is attracted to the anions, leaving an adsorbed monolayer of only cations.…”

A novel additive sodium diisopropylnaphthalene sulfonate (SDIPNS) was investigated in Zn-Mn electrodeposition on steel from chloride bath. To this end, cyclic voltammetry was performed in absence and presence of SDIPNS to study different electrochemical systems. Electrochemical data showed that SDIPNS increases Zn deposition overpotential, resulting from strong adsorption of SDIPNS molecules on the cathode surface. The effects of scan rate, switching potentials on the electrochemical behavior of Zn-Mn co-deposition were investigated. The variation of scan rate reveals that the Zn-Mn co-deposition is associated with charge transfer coupled with the mass transfer. SDIPNS concentration was investigated with regard to the Mn content in the final coatings. The chemical composition result showed that Mn-rich deposits, containing 20 wt.% of Mn, are successfully deposited under low cathodic potential (E = − 1.52 V vs. Ag/AgCl). The surface characterization of Zn-Mn coatings was explored by scanning electron microscopy (SEM). The presence of SDIPNS in the electrolytic bath permits to obtain compact, well adherent, and fined grain Mn-rich alloys.

“…So, in [22,23], for electrodeposition of zinc on carbon steel (AISI 1018), additives of quaternary ammonium compounds were used to obtain compact coatings. Nbenzyltriethylammonium chloride and tetrabutylammonium hydroxide additives inhibit the growth of dendrites and can be used as a leveling additive, whereas in the case of tetraethylammonium hydroxide this effect is negligible [24].…”

In this paper, the electrochemical reduction of indium on a glassy carbon electrode (GCE) in a chloride electrolyte in the presence of tetrabutylammonium chloride (TBACh) was studied using the rotating disk electrode method, chronoamperometry and scanning electron microscopy. It was found that the addition of TBACh inhibits the electroreduction of indium by increasing the activation energy of the process by 17 kJ mol-1 , and also shows leveling action at its low concentrations. The diffusion coefficient of indium (III) ions found from Levich equation at 25°C, was 4.93× 10-6 cm 2 s-1. The In 3+ diffusion coefficient determined using the Levich equation are consistent with the values determined by the Cottrell law and universal Stokes-Einstein equation. The addition of 10-4 M TBACh to the electrolyte reduces the diffusion coefficient to 2.13× 10-6 cm 2 s-1 .
