用X-射线光电子能谱仪（XPS）分析了腐蚀银片表面的腐蚀产物。结果表明：活性硫化物是造成喷气燃料银片腐蚀不合格的主要原因。考查了添加剂的抗腐蚀性能和热稳定性以及添加剂对喷气燃料热氧化安定性、磨擦学性能和水分离指数的影响。同时对添加剂的抗腐蚀作用机理进行了研究，DMTD衍生物添加剂在油相中可捕集活性硫，生成非腐蚀性硫化物，抑制银片腐蚀。
The corrosion product on the surface of silver was analyzed by means of XPS. The results indicated that the unqualification of silver strip corrosion of jet fuel was caused by the active sulfides. The anticorrosion property and thermal stability of inhibitor have been investigated, the influence of the inhibitor on thermal oxidation stability of jet fuels, wear performance and water separation characteristics was investigated. The anti-corrosion mechanism for the inhibitor was studied, the reaction of DMTD derivative with the active sulfides in oil phase produce non active sulfides, thus, the silver strip corrosion was inhibited.
