“…Gluconate solutions represent relatively new type of the electrolytes for tin [6,11] and tin alloys deposition [14][15][16][17][18]. Sodium gluconate is a cheap and environmentally safe additive, which can form soluble complexes with a variety of metal ions in both slightly acidic and alkaline baths.…”

Electrodeposition of tin from acidic gluconate baths (chloride, chloride-sulfate) was investigated. Equilibrium distribution of tin(II) species in both solutions was calculated. Cyclic voltammetric, potentiostatic, and galvanostatic measurements showed that cathodic process can run under limiting current due to the presence of tin complex electroactive species. Average effective diffusion coefficients of metal species were determined. Nucleation of tin occurred through a progressive three-dimensional diffusion growth model. A characteristic of tin deposits was also presented.

“…These studies using a flow circulation electrodeposition cell system at 20 • C are an extension of earlier research using gluconate electrolytes where optimum results using a static electrolyte cell system involved high temperature deposition at 60 • C to obtain good quality metallic deposits [1][2][3][4]. In these studies the basis of the electrodeposition process was one which was environmentally safe and acceptable as a scale up industrial process.…”

This study involved the use of a flow circulation cell, using varying circulation rates as a room temperature process (20 • C). Mössbauer and XRD analysis were conducted to ascertain whether amorphous or microcrystalline structures could be obtained at 20 • C using a range of current densities. Amorphous or microcrystalline structures of Sn-Fe and Sn-Co-Fe have potentially important industrial applications for energy efficient cells, for use as high performance electrodes in lithium batteries, as environmentally acceptable corrosion resistant materials and are derived from an energy efficient environmentally friendly electrolyte process which would be acceptable as an industrial process. 57 Fe and 119 Sn Mössbauer investigations supported by XRD analysis confirmed that the room temperature flow circulation cell gave rise to previously unknown non-equilibrium amorphous structures which do not occur in the corresponding thermally prepared alloys as shown in the thermal equilibrium diagrams. Mössbauer analysis shows these alloys to be both amorphous and ferromagnetic. It is shown that the flow circulation cell used at 20 • C based on the 2 M. El-Sharif et al. environmentally friendly gluconate bath reported gives amorphous based Sn-Fe and Sn-Co-Fe alloys over a useful range of current densities facilitated by using a range of circulation rates.

“…The increase in intensity of the fcc diffraction peak as the applied potentials were increased indicates that nickel content was increased. The existence of only fcc crystal structure is strongly believed due to less Fe content in the films [35], as shown in Fig. 6.…”

The aim of this study was to produce thin films of ternary cobalt-nickel-iron (Co-NiFe) alloy by electrochemical deposition method at different electrodeposition potentials in a sulfate solution (0.15 M CoSO 4 + 0.2 M NiSO 4 + 0.005 M FeSO 4 ). The Co-Ni-Fe alloy thin films were electrodeposited on indium-doped tin oxide (ITO) coated on a conducting glass substrate. Voltammetric studies indicated the potential range between -1.10 to -1.30 V (SCE) for successful deposition of Co, Ni and Fe. The energy dispersive X-ray (EDX) analysis indicated that the films exhibited anomalous behavior with Ni content significantly increased, whereas the Co and Fe content decreased as the electrodeposition potentials reached more negative values. The scanning electron microscopy (SEM) study showed that the electrodeposited films were uniform for all applied potential values and larger particles were formed when higher electrodeposition potentials were applied. Investigation by X-ray diffraction (XRD) revealed that the dominant phase in the deposited film was amorphous Co-Ni-Fe. Hysteresis curves of the ternary alloy film obtained from vibrating sample magnetometer results prove that the alloy is ferromagnetic. The coercivity mechanism of the Co-Ni-Fe films has obeyed Neel's relation which is thickness dependence.
