TIN ELECTRODEPOSITION ON CARBON STEEL. THE INFLUENCE OF THE CONCENTRATION, ADDITIVES AND OF THE METHOD

Tin electrodeposition onto carbon steel from SnCl2 solutions at different concentrations was evaluated in the absence and the presence of boric acid, ammonium citrate, tartric acid and sodium chloride. The phase formation of tin film onto a carbon steel electrode was investigated using: linear voltammetry, linear potentiometry, chronoamperometry, normal and differential pulse voltammetry.
