In the present study an attempt was made, using cyclic and linear sweep voltammetryto explore the effects of Linseed oil extract additive on the electrodeposition of tin on mild steel in acid sulfutic solution. The experiments were performed under different plating time, different additive concentrations and fixed pH conditions. Tin electrodeposition on mild steel was performed using a DC - supply at defined operating parameters. The electrodeposition process was sensitive to the changes in the additive concentration and plating time. Polarization curves and electrochemical impedance spectroscopy demonstrated that corrosion current density decreased and charge transfer resistance increased in the presence oflinseed oil in the electrolyte bath.
