| Abstract: | Some 5-arylamino-2-mercapto-1,3,4-thiadiazole additives, blended with lithium grease (0.5, 1.0, 1.5 & 2.0% w/w) have been evaluated as extreme pressure additives in a four-ball test. The additives lower friction as well as wear and function well even at high temperature and pressure as compared to commercially available lithium base EP grease. The blended greases were found to pass corrosion, oxidation stability as well as roll stability tests. The 2% w/w admixture of 5-p-methoxyphenylamino- 2-mercapto-1,3,4-thiadiazole with lithium grease exhibited a weld load of 360 kgf,whereas, the reference lithium base EP grease and lithium grease without additive afforded the weld load values of 260 and 160 kgf, respectively. The topography and tribochemistry of the used balls after four-ball test were studied using scanning electron microscopy and EDAX techniques, respectively. The EDAX analysis showed the presence of sulphur in the wear tracks and it was found to enhance the EP activity of the additives. |
