| 摘 要： | 采用增重法和金相显微技术，研究了不同浓度的沉降硫-石油醚溶液对银片的腐蚀作用，以及噻二唑型缓蚀剂TSJ-T6在不同浓度、不同温度下的缓蚀效率。 研究表明，TSJ-T6缓蚀剂对银片具有很好的缓蚀性能，且随着缓蚀剂浓度的增加，缓蚀效率也随之提高，当缓蚀剂浓度达到10.0 μg/g时，缓蚀效率达到94.37%。 经过吸附等温线拟合，得到缓蚀剂TSJ-T6在银片表面的缓蚀符合Langmuir吸附等温式，吸附过程为放热反应过程。

| Abstract: | The inhibitive action of a composite thiadiazole inhibitor(TSJ-T6) against the corrosion of silver in solutions of simulation jet fuel has been studied using the method of mass gain and metallographic microscopy. All experimental results showed that TSJ-T6 has an excellent corrosion inhibition performance and the most effective concentration of inhibitor is 10.0 μg/g, when the inhibition efficiency can reach 94.37%. The adsorption of TSJ-T6 on the surface of silver strip obeys the Langmuir adsorption isotherm, and the thermodynamic parameters were determined and discussed. The kinetic parameters were calculated by the obtained corrosion inhibition rates at different temperatures. |
