“…Electrodeposition of tin from methanesulfonic acid baths containing polyethlene glycol, polypropylene glycol and phenolphthalein has shown that the PPG molecule is likely to enhance the adsorption of PEG on the electrode surface and phenolphthalein helped to produce a smooth and matte surface finishes. 46 The adsorption of these additives minimized the hydrogen evolution reaction rate, thus the grain sizes and surface roughness of the deposits are reduced.…”

Highlights Types of aqueous electrolytes for pure tin deposits are reviewed. The many existing and developing applications of tin deposits are summarised. Emphasis is placed on versatile methanesulfonic acid electrolytes. The effects of bath composition (including additives) and operating conditions on deposit morphology are illustrated. Electrochemical studies at static and controlled flow rotating electrodes are illustrated. AbstractThe importance of tin and its electrodeposition are summarised and the scope for plating tin is outlined.Established applications of electroplated tin include corrosion protection, electronics fabrication and cooking utensils. The past 20 years have seen developments in the science and technology of tin plating, including research into nanostructured deposits, adoption of environmentally friendly methanesulfonic acid baths and more ambitious coatings including multi-layers and composites. Our ability to tailor deposit structure and composition has been improved by newer electrolytes, pulse plating and electrolyte additives. The diversity of tin applications has extended to lithium batteries using newer structures (such as composites, multi-layers and nanostructures), electrical control (e.g., pulsed current) and relative bath/electrode movement (including the use of rotating electrodes). Electrochemical aspects of modern tin deposition are illustrated by data from the authors' laboratory which highlights the versatility of methanesulfonic acid electrolytes. A wide range of deposit morphology, colour and surface finish are possible by the use of suitable addition agents and control of electrode/electrolyte movement and operating conditions. Subject areas needing further research work are identified.

“…The deposits obtained under such conditions are porous, coarse and poorly adherent with formation of needles, whiskers and dendrites that cause short circuits between anode and cathode [4][5][6][7][8][9]. Various organic additives such as surface active agents like cetyl tetraalkyl ammonium bromide, aromatic carbonyl compounds, and amine-aldehyde reaction products, methane sulphonic acid and its derivatives, etc.…”

Effect of additives on electrodeposition of tin and its structural and corrosion behaviour

The present investigation deals with the electrodeposition of tin from chloride electrolytes. Gelatin, b-naphthol, polyethylene glycol, peptone and histidine were used as additives in the plating bath to improve the surface morphology, grain size, smoothness and corrosion resistance of the tin deposits. XRD data obtained for electrodeposited tin show polycrystalline nature with single b-phase and tetragonal structure. A uniform and pore free surface was observed under SEM analysis. AFM results indicate the grain refining brought about by the additives. Corrosion rate measurements using the Tafel extrapolation method and electrochemical impedance spectroscopy reveal the increased corrosion resistance from baths containing additives.

“…Benzaldehyde (BA), like some other organic substances containing double bonds, aromatic rings, aldehyde groups etc. [1][2][3][4][5][6][7][8][9][10] is able to act as a brightener. To improve the operating characteristics of plating baths and the properties of the resulting coatings, certain surfactant combinations are usually applied.…”

Cu(II) and Sn(II) reduction in acid sulphate solutions containing polyether laprol DS-10 and benzaldehyde (BA) was studied by means of impedance, voltammetric, XPS and XRD techniques. Both additives demonstrate weak surface activity on copper substrate in Cu(II) solutions in the absence of halide impurities. In contrast, their effect is overwhelmingly higher in the Sn|Sn(II) system. The additives induce a significant increase in Sn-electrode impedance and simultaneous strong inhibition of Sn(II) reduction over a wide range of cathodic polarizations. The effects of sintanol and BA in mixed Cu(II) and Sn(II) solutions demonstrate a kind of synergism. Underpotential deposition of tin on foreign (copper) substrate is observed at potentials more positive than the equilibrium potential of the Sn|Sn 2? system. Incorporation of tin into the Cu crystalline lattice results in the formation of multiphase material containing pure copper, a-CuSn phase, and intermediate hexagonal hcp phase. Formation of the pure tin phase occurs at more negative potentials and results in a strong inhibitive adsorption that manifests itself in the development of a deep voltammetric minimum. The tin content in the coatings depends on BA concentration and, particularly, on the electrode potential.
