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10.0μg/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。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.
