In this study, nanocrystalline aluminium alloy was produced from metallic powders with addition of 10wt. %Fe and 5wt. %Cr processed using mechanical alloying (MA) technique. The initial powders were processed in a planetary ball mill for 150 hours at room temperature in an inert atmosphere. The processed powders were consolidated and sintered using a high frequency induction heat sintering (HFIHS) machine to form bulk samples. The crystallize size of the bulk samples was calculated from the peak profile obtained through X-Ray diffraction (XRD). The corrosion resistance of nanocrystalline aluminium alloy was studied in 3.5% NaCl solution at room and higher temperatures using electrochemical impedance spectroscopy (EIS) and linear polarization resistance (LPR) techniques. Linear polarization resistance curves, Nyquist data and Bode curves obtained by electrochemical impedance spectroscopy, suggest that the alloy have good resistance to corrosion in sodium chloride solution at room temperature as well as at higher temperatures.

Keywords: Nanocrystalline aluminium alloy, mechanical alloying, corrosion, polarization, EIS
