Abstract
Similar welds composed of 5083 were produced by friction stir welding. In the solution of 0.2 M NaHSO3 and 0.6 M NaCl, with the addition of a given concentration sodium molybdate as the inhibitor, the electrochemical corrosion behaviors of the friction stir welds (FSW) and 5083 were comparatively investigated by potentiodynamic polarization curve tests and electrochemical impedance spectra (EIS) for different test temperatures (herein, 25°C,30°C,35°C,40°C). The results indicated that at 30°C, the anti-corrosion property of 5083 FSW weld and parent material was superior to those of the other temperatures.
