摘要：采用失重法、电化学极化曲线和电化学阻抗谱考察了 0 .5 mol/ L HCl溶液中 2 -巯基苯并咪唑 (MBI)和 1 -苯基 -5 -巯基 -四氮唑 (PMTA)对铜的缓蚀作用。MBI和 PMTA的加入使铜的自腐蚀电位正移 ,对铜电极的阳极腐蚀过程存在抑制作用。两者复配使用增强了对铜电极的阳极和阴极电化学过程的抑制作用 ,提高了铜电极膜电阻 ,从而具有较好的缓蚀协同效果。
The corrosion inhibition of 2 mercapto benzimidazole (MBI) and 1 phenyl 5 mercapto tetrazole (PMTA) for copper in 0.5mol/L HCl solution were investigated by weight loss measurements and electrochemical methods (potentiodynamic polarization and impedance spectroscope). Coupon tests show that the inhibition efficiency of MBI is 91.6% at 10 -3 mol/L level. Potentiodynamic polarization results reveal that the two compounds act as anodic inhibitors. Inhibition of the complex of MBI and PMTA was also studied. There is a synergistic effect for the best protection at the molar ratio of 1:2 between MBI and PMTA.
