摘要
通过测量Al—Zn-In—Si-Mg合金在不同浓度NaCl溶液中的交流阻抗谱图,研究了Cl^-浓度和浸泡时间不同对铝合金表面膜阻抗的影响。结果表明:随溶液中Cl^-浓度增加,表面电阻Rt减小,而表面电容Cd增大;Rt和Cd随浸泡时间的变化,视Cl^-浓度不同,有不同的变化趋势。
The A. C. impedance curve of Al-Zn-In-Si-Mg alloy has been measured in Nad solutions. The influence of Cl- concentration and exposure time on the surface film has been studied. The results show that film resistance Rt decreases and double layer capacitance Cd increases Cl- concentration. The tendency of variations in Rt and Cd are different with a change in exposure time in different Cl- concentration.
