ABSTRACT:
Background:
Tin have been electrodeposited from an aqueous sulfuric acid electrolyte in the presence and without Nigella sativa under different parameters and conditions

Material and methods:
The experiments were performed under different plating time, different current densities, pH and temperature conditions and cyclic and linear sweep Voltammetry, DC - supply at denoted operating parameters. The surface morphology of the deposited tin from baths with NS, and NS-free, under 15 mA.cm-2, pH = 0.4, 25°C and ∆t = 10 min was examined by scanning electron microscopy (SEM)

Results:
The cyclical and linear sweep Voltammetry have confirmed the effect of the additive on the kinetics during the process of reduction and dissolution of forming metal. The additive induced an increase of the activation energy and of the vervoltage of the reaction of stannous and the hydrogen evolution. Characterization of the tin plated surface of the mild steel substrate showed a different surface morphology depending on plating conditions. The electrodeposition process is sensitive to changes in pH and applied current density

Conclusions:
The quality of the electro-deposition of tin, in the presence of Nigella sativa, was good as indicated by the microstructural morphology of the plated surface except for the few porosities demonstrated
