摘要：

Similar welds composed of 5083 were produced by friction stir welding. In the ambient solution of 0.2 mol/LNaHSO3 and 0.6 mol/L NaCl, the electrochemical corrosion behavior of the friction stir welds (FSW) and 5083 was comparatively investigated by static weight loss experiments and potentiodynamic polarization curve tests at ambient temperature. The results indicate that the average corrosion rate of the weld is less than that of 5083. Then, sodium molybdate was added to the corrosive solution and its effect on the corrosion behavior of the weld and parent metal was comparatively assessed. The inhibition efficiency (IE) for the weld is beyond that for 5083 base materials, and sodium molybdate may be thought of as an effective inhibitor.
