Title: EIS parameters and cell spacings of an Al-Bi alloy in NaCl solution
Author: Osorio, WR

Abstract: This present study is focused on the evaluation of the effect of the cell spacing of as-cast Al-2 wt.% Bi alloy formed by droplet-like bismuth particles distributed in the Al matrix, on the corrosion response. EIS parameters and polarization curves obtained in a 0.5 M NaCl solution at room temperature are discussed. It was found that with the decrease in the cell spacing, the corrosion current density and polarization resistance increases and decreases, respectively. This corrosion behavior was attributed to strains that are generated at the borders between the Al-matrix and droplet-like Bi particles. (C) 2013 Elsevier Ltd. All rights reserved.
