| Abstract | |
The aim of this study is to determine the effect of the resulting microstructural array of an as-cast Al-1 wt% Fe-1 wt% Ni alloy on its electrochemical corrosion behavior in a stagnant and naturally aerated 0.5 M NaCl solution at room temperature. Electrochemical impedance spectroscopy (EIS) plots, potentiodynamic polarization curves, and equivalent circuits are used to evaluate the corrosion response. It was found that nanosized Al9FeNi intermetallic (IMC) particles have an important role on the corrosion resistance, which significantly affect the anode/cathode area ratio and as consequence, the examined electrochemical parameters. A mixture of interconnected spheroids and fiber-like IMC particles induces a drastic and rapid increase in the current density, while intermittent IMC particles reduce the corrosion action. (AU) | |
