摘　　要：采用塔菲尔(Tafel)曲线法和电化学阻抗法(EIS)2种电化学方法评价了4种不同型号的电子电气缓蚀剂在天然海水中对T2铜合金、H62铜合金以及2Al2-T4铝合金的缓蚀效果。对于T2铜合金,缓蚀剂的缓蚀效率从高至低依次为DZ-1、TFHS-20、DJB-823、WD-40;对于H62铜合金,缓蚀效率从高至低依次为DZ-1、DJB-823、WD-40、TFHS-20;对于2Al2-T4铝合金,缓蚀效率从高至低依次为DZ-1、WD-40、DJB-823、TFHS-20。4种缓蚀剂中,DZ-1缓蚀剂Tafel曲线法和EIS法得到的缓蚀效率都高于99.5%,所以,对于T2铜合金、H62铜合金以及2Al2-T4铝合金3种金属材料来说,DZ-1是4个型号的缓蚀剂中效果最优的。The corrosion inhibition effect of four electronics corrosion inhibitors on T2 copper alloy, H62 copper alloy and 2Al2-T4 aluminum alloy in natural seawater is evaluated by Tafel curve method and electrochemical impedance spectroscopy(EIS). The results show that the corrosion inhibition efficiency order of corrosion inhibitors from highest to lowest is DZ-1,TFHS-20, DJB-823, WD-40 to T2 copper alloy, DZ-1, DJB-823, WD-40, TFHS-20 to H62 copper alloy, and DZ-1, WD-40,DJB-823, TFHS-20 to 2Al2-T4 aluminum alloy. Among the four corrosion inhibitors, both Tafel curve method and EIS of DZ-1 corrosion inhibitor have higher corrosion inhibition efficiency than 99.5%, so for T2 copper alloy, H62 copper alloy and2Al2-T4 aluminum alloy, DZ-1 is the optimum corrosion inhibitor among the four corrosion inhibitors.
