Resumen
A comparative experimental study on the electrochemical behaviour of a Pb-1wt.%Sb alloy is carried out in a 0.5M NaCl and a 0.5M H2SO4 solutions at room temperature. A water-cooled unidirectional solidification system was used to obtain the Pb-Sb alloy samples used in the corrosion tests. Electrochemical impedance spectroscopy (EIS) plots, potentiodynamic polarization curves and an equivalent circuit analysis were used to evaluate the electrochemical behaviour. The experimental current density decreased with the increase in the cellular spacing, independently of the nature of the applied electrolyte. Hence, a dilute Pb-Sb alloy having coarse cell spacings has higher electrochemical corrosion resistance. © 2011 Elsevier Ltd. 34
