| Abstract: |
| The influential factors such as surface state of working electrode, the chloride concentration, and pH value on AA5083 electrochemical behavior in 3.5% NaCl solution were investigated using potentiodynamic polarization and cyclic polarization experiment. The results showed that the Epit and Ecor potentials shift to positive values when specimen surface is polished;Eb shift to positive significantly with decrease of chloride concentration; chloride concentration has little influence onEb when the concentration exceeds1.0%; pH and other ion concentration has influence on Epit andEp. |
