| 中文摘要: |
| 采用动电位扫描及循环伏安试验方法，研究了工作电极表面状态、Cl-浓度、pH值等因素对5083铝合金在质量分数为3.5%的NaCl溶液中电化学性能的影响。研究结果表明，试样表面进行抛光后，点蚀电位变正，点蚀保护电位正移。随着Cl-浓度的降低，点蚀电位Eb明显正移；当Cl-浓度超过1%（质量分数）后，Cl-浓度对Eb的影响则不明显。溶液的pH值及其它阴离子的添加均会对5083铝合金点蚀电位及保护电位产生影响。 |
| 英文摘要: |
| 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. |
