过氧乙酸对ADC12铝合金钝化行为的研究

Effect of Peracetic Acid Passivation on Corrosion Resistance of ADC12 Aluminum

摘要: 本文通过极化曲线、交流阻抗比较分析不同质量分数过氧乙酸对ADC12铝合金抗腐蚀能力，并讨论其抗腐蚀机理。实验结果表明，过氧乙酸对ADC12铝合金表现出钝化效果，极化曲线测试结果同时表明不同质量分数的过氧乙酸对ADC12铝合金在酸雨介质中的钝化效果由高到低依次为2%，1.5%，1%，3%。
>The passivation effect of peracetic acid on the corrosion of ADC12 aluminum has been investigated through potentiodynamic polarization, electrochemical impedance spectroscopy (EIS) and the reaction mechanism has been explored. The results show that peracetic acid has effect on corrosion resistance of ADC12 aluminum. Polarization measurements suggest that after passivation, the corrosion rate of the electrode in acid rain solution from high to low is mass fraction of 2%, 1.5%, 1%, 3%.
