通过腐蚀失重法、电化学法和扫描电镜等方法研究了双苯并咪唑化合物(BBB)对碳钢在0.25 mol/LH_2SO_4溶液中的缓蚀行为.结果表明,双苯并咪唑化合物缓蚀性能优异,缓蚀效率随缓蚀剂浓度增大而升高,且为同时抑制碳钢腐蚀阴阳极过程的混合型缓蚀剂.在碳钢表面的吸附符合Langmuir等温吸附规律. |

The corrosion behavior of Q235 mild steel in 0.25 mol/L H_2SO_4 solution with the addition of bis-benzimidazole as an inhibitor was investigated by mass loss,electrochemical methods and electron scanning microscopy(SEM).The results showed the compound exhibited excellent corrosion inhibition performance,and the inhibition efficiency increased with the increase of the compound concentration.The compound acted as a mixed-type inhibitor by suppressing both anodic dissolution and cathodic hydrogen reduction processes simultaneously.The adsorption of the compound on mild steel surface followed the Langmuir isotherm. |
