Abstract：In this work, corrosion inhibition of thiadiazole derivatives , namely 2,5-dimercapo-1,3,4 -thiadiazole (DMTD) and 5-methyl-2-mercapto-1,3,4 -thiadiazole (MMTD) in jet fuel containing H2S was studied.Corrosion of silver test results indicated that:adding 40 mg/L thiadia20le derivatires, the inhibition of silver significantly enhanced .The electrochemical measurement showed that: adding inhibiters significantly decreased the anodic and cathodic polarization corrosion current density , and efficiency of MMTD is better than DMTD.3D profiler and scanning electron microscopy (SEM) carried out to analyze the silver strip after corro-sion in without and with addictives .The results can be clearly shown that DMTD and MMTD molecules are strongly adsorbed onto silver strip surface .These compounds decreased silver strip corrosion .
