Tribological study of novel S- N style 1,3,4- thiadiazole- 2- thione derivatives in rapeseed oil

김 준 호

Two non- phosphorus and ashless 1,3,4- thiadiazole- 2- thione derivatives, 5- dodecyldithio- 3- phenly- 1,3,4- thiadiazole- 2- thione (DPTT) and 5- cetyldithio- 3- phenyl- 1,3,4- thiadiazole- 2- thione (DHTT), were synthesized and their tribological behaviors as additives in rapeseed oil (RSO) were evaluated using a four- ball friction and wear tester.

It is supposed that the synthetic additives adsorb and react with the steel surfaces during the rubbing process and generate a surface protective film composed of sulfate, sulfide, iron oxide and organic nitrogen containing compounds
