The Fe-based amorphous alloy was prepared by melt spinning and its microstructure was analyzed by X-ray diffraction and transmission electron microscopy. Electrochemical tests were carried out in 1 M NaOH solution using cyclic voltammetry and electrochemical impedance spectroscopy. The results indicated that the Fe-based amorphous alloy exhibited good corrosion resistance in alkaline solution. The magnetic field had a notable effect on the corrosion resistance of the Fe-based amorphous alloy. When the magnetic field intensity was 0.5 T, the corrosion resistance of the alloy improved significantly.IntroductionFe-based amorphous alloys have attracted a great deal of attention due to their excellent mechanical properties, high corrosion resistance and good soft magnetic properties [1-3]. The application of Fe-based amorphous alloys has been extended to various fields such as aerospace, biomedical engineering, and energy storage [4-6]. In recent years, the effect of magnetic field on the electrochemical behavior of metallic materials has been widely studied [7-9]. However, the effect of magnetic field on the corrosion resistance of Fe-based amorphous alloys in alkaline solution has not been thoroughly investigated. Therefore, in this study, we investigated the electrochemical behavior of Fe-based amorphous alloys in alkaline solution and the effect of magnetic field on its corrosion resistance.Materials and MethodsThe Fe-based amorphous alloy was prepared by melt spinning.
