| 目的 对Cu-MOF进行复配，探究其最佳复配比例，以增强Cu-MOF的缓蚀效果。方法 通过静态失重挂片、电化学测试和表面形貌分析等手段，探究Cu-MOF与硫脲、六亚甲基四胺复配前后对Q235碳钢在1 mol/L HCl介质中缓蚀行为的变化。结果 单独使用50 mg/L的Cu-MOF时，碳钢的腐蚀速率为2.83 g/(m2.h)。使用硫脲、六亚甲基四胺与Cu-MOF进行复配后，碳钢在盐酸介质中的失重腐蚀速率均有了不同程度的下降，分别下降至1.28、1.14 g/(m2.h)。结论 硫脲和六亚甲基四胺与Cu-MOF复配，表现出很好的协同作用，碳钢表面形成的保护膜更加致密，缓蚀效率明显提升。 |

| Thepurpose of this paper is to explored the optimal compounding ratio by compounding Cu-MOF,thereby obtain better corrosion inhibition effects of Cu-MOF. The corrosion inhibition behavior change of Cu-MOF before and after compounded with thiourea and hexamethylenetetramine on Q235 carbon steel in 1 mol/L HCl medium was investigated by the means of static weight-loss coupon test, electrochemical measurements and surface morphology analysis. When 50 mg/L Cu-MOF was used alone, the corrosion rate of carbon steel was 2.83 g/(m2.h). After using thiourea and hexamethylenetetramine with Cu-MOF for compounding, the weight-loss corrosion rate of carbon steel in hydrochloric acid solution has decreased with varying degrees, to 1.28 and 1.14 g/(m2.h) respectively. The compounding of thiourea and hexamethylenetetramine with Cu-MOF showed good synergistic effect. The protective film formed on the surface of carbon steel was denser and the corrosion inhibition efficiency was significantly improved. |
