Abstract

This article studied corrosion behavior of steel and sacrificial anode on ship's shell in the clean and polluted water of Thi Vai River at room temperature by mass loss, potentiodynamic polarization and electrochemical impedance spectroscopy methods. The experimental results showed that the life of ship's shell was dropped about two times by wastewater, which discharged into the Thi Vai River. Authors proposed some suggestions to resolve the serious problem.
