| Description |
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.
