dc.descriptionThe aim of this study is to evaluate the effect of different macro-morphologies of an as-cast Pb1wt.%Sn alloy on the electrochemical behaviour in a 0.5 M H(2)SO(4) solution at 25 degrees C. Equiaxed and columnar morphologies containing coarse and fine cellular spacings were produced. Cylindrical permanent low-carbon steel and a water-cooled unidirectional solidification system were employed permitting the polidirectional and unidirectional samples be produced, respectively, and to be experimentally examined as a function of the grain size. Electrochemical impedance spectroscopy (EIS) diagrams, potentiodynamic polarization curves and an equivalent circuit analysis were used to evaluate the electrochemical response. It was found that an equiaxed macrostructure, independently of having coarse or fine grains, tends to yield higher corrosion resistance than a columnar macrostructure. The pre-programming of the macromorphology of as-cast Pb-Sn alloys can be used as an alternative way to produce components of lead-acid batteries with improved electrochemical corrosion behaviour
