Cu₆₀Zr₃₀Ti₁₀ (at. %) ribbon was prepared by melt spinning. Its glassy structure was confirmed by X-ray diffraction (XRD). Its corrosion behavior in HCl and NaCl solutions was investigated by electrochemical polarization measurement. The surfaces before and after corrosion were observed with scanning electron microscope (SEM) and analysis was performed using electron dispersive spectroscopy (EDS). The results show that the decrease of current density is due to the formation of a mixture of simple oxides or complex oxidic compounds. In both cases, the corrosion potential decreases with increasing chloride concentration. The passive film forms easier in HCl than in NaCl. In addition, the higher is the chloride concentration, the easier is the passivation.
