【 摘 要 】

Corrosion behaviors of pure Cu and Cu-Ni-Zn alloy were investigated in 3.5% NaCl solution and artificial seawater by electrochemical impedance spectroscopy and potentiodynamic polarization technologies, and the corrosion morphologies were observed by field emission scanning electron microscopy. The results revealed that Cu-Ni-Zn alloy possessed better corrosion resistance than that of pure Cu in both 3.5% NaCl solution and artificial seawater. The corrosion morphology displayed the corrosion product films on Cu-Ni-Zn alloy were more compact and uniform than that on the pure Cu in both 3.5% NaCl and artificial seawater media.
