The Influence of Prepared Methods on Electrochemical Corrosion Behavior of Fe3Al Intermetallic

Abstract

Different compositions to prepare the Fe3Al intermetallic were analyzed through the microstructure and electrochemical corrosion behavior. The structure and microstructure were analyzed by X-ray and scanning electron microstructure (SEM). The corrosion resistance of samples was evaluated by potentiodynamic polarization (Tafel) and electrochemical impedance spectroscopy (EIS). Results show that the alloy with a composition of pure aluminum with pure iron shows a higher corrosion resistance.
