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.
