Abstract

Two ashless triazine derivatives, 2,4-bi-amido-6-(O,O′-di-i-octhyl dithiophosphate)- 1,3,5 - triazine were synthesized. Their tribological properties as lubricating oil additives compared with ZDDP in hydrogenated oil were evaluated using a four-ball tester. The results show that these triazine derivatives possess extreme pressure capacity, and they can improve antiwear and friction-reducing performance of base stock than that of ZDDP. Their tribological performance is corresponding to the amide. The elements chemical states of the worn surface were estimated through X-ray photoelectron spectroscopy (XPS) and scanning electron microscope (SEM). The results show that a protective film containing sulphide, phosphate and some organic nitrogen compounds was formed on the worn surface during the lubrication process, and the film possesses extreme pressure and antiwear properties.
