The corrosion behavior of Fe78Si9B13 glassy alloy ribbons with various circumferential speeds (SC) in NaCl solutions has been investigated. With increasing SC, the corrosion potential of samples increases, while the pitting potential decreases in polarization process. Thickness of oxidation film decreases with increasing SC. The Si distribution on corroded surfaces depends on the quick growth of iron oxides. The maximum immersion corrosion rate occurs at 0.6 M NaCl, which is associated with the chloride concentration and stress. The unique corrosion behavior in 0.6 M NaCl is helpful to study the corrosion resistance of Fe-based alloys in seawater environment.
