dc.description.abstractAluminum alloys with silicon as a major alloying element constitute a class of materials, which provides the most significant part of all shaped castings manufactured. Such alloys have a wide range of applications in the automotive and aerospace industries. The literature presents contradictory results and no satisfactory explanations concerning to resulting microstructures provided by laser surface remelting (LSR) and its effect on the electrochemical behavior of Al-Si alloys. The aim of this study was to investigate the effect of microstructural refinement by LSR on corrosion resistance of an Al-9 wt%Si casting alloy. As-cast samples were subjected to a continuous 1 kW CO2 laser. Corrosion resistance has been analyzed by an electrochemical impedance spectroscopy (EIS) technique and polarization curves carried out in both 0.5 M NaCl and 0.5 M H2SO4 solutions at 25 °C. An equivalent circuit has also been proposed and impedance parameters were simulated by the ZView® software. It was found that the structural modification provided by the LSR process induces a decreasing effect on the corrosion resistance when compared to that of the untreated sample. © 2007 Elsevier B.V.
