摘要：

Cu55Zr35Ti10 (at. %) ribbon was prepared by melt spinning. Its glassy structure was confirmed by X-ray diffraction (XRD) and differential scanning calorimetry (DSC), respectively. Its corrosion behavior in HCl and NaCl solutions was investigated by electrochemical polarization and immersion measurements. The surfaces before and after corrosion were observed with scanning electron microscope (SEM). The corrosion potential and corrosion resistance of the Cu55Zr35Ti10 metallic glass both decrease with increasing chloride concentration, and are higher in NaCl than in HCl. The current density in anodic curve sharply decreases when the potential reaches up to a value and the chloride concentration is more than 0.5 M in both HCl and NaCl solutions. The different corrosion behavior in HCl and NaCl is also carefully discussed. (c) 2012 Elsevier B.V. All rights reserved.
