The impact of the type 3 ionic liquid viscosity on the electroplating process of SN, ZN and ZN SN alloys

Abstract EN

In this study the impact of type 3 ionic liquid viscosity investigated on the electroplating process of alloys.

Three different composition of type 3 ionic liquid were used by altering the molar ratios and type of hydrogen bond donor applied with 1mol of quaternary ammonium salt choline chloride in the preparation process as follow:1 mol ChCl:2 mol urea(Reline),1mol ChCl:1mol urea:1mol ethylene glycol(Hybride) and 1mol ChCl: 2 mol ethylene glycol(Ethaline).

It had been shown that the electrodeposition process differ widely by the change in the ionic liquid’s viscosity.

Also it was found that the oxidation and reduction potentials peaks of ?? − ?? ??? ??/?? alloys were shifting to high negative values when the ionic liquid was changed from ethaline to reline and hybride.

Hybride and reline had higher viscosity than ethaline so there was a shift in the oxidation and reduction potential peaks of metal species.

The difference in the electrodeposition process of ??, ?? ??? ??/?? alloys has been shown in this research.

Surface morphology has been studied by SEM (scanning electron microscopy) for each of the above metals both individually and as alloys.

In addition, elemental analysis was carried out along with SEM by using energy dispersive analysis by X-rays (EDAX) for coated zinc and tin both as individual and as a mixture after their surface morphologies were determined.

Finally, cyclic voltammetry for zinc and tin was conducted in each individual ionic liquid by Ivion potential instrument and their voltammograms have been determined.

The effect of altering the viscosity of the ionic liquid on the reduction and oxidation potentials’ peaks of zinc and tin were also examined both separately and as alloys
