Potentiodynamic polarization studies were performed on the air side and wheel side of the specimen in 1 M NaCl aqueous medium at room temperature. It was observed that the corrosion current density on the air side of the specimen was less than that of the wheel side of the specimen in 1 M NaCl aqueous medium. The amorphous nature of the air side and wheel side of the specimen was confirmed by X‐ray diffraction (XRD). The observed behaviour can be related to the surface morphology due to processing of the ribbons. It is suggested that the inferior corrosion resistance of the wheel side surface is attributed to higher concentration of quenched‐in defects due to higher cooling rate. Weight loss studies were also carried out in order to corroborate the polarization results. The results are discussed in the paper in the light of data reported in the literature.
