【Abstract】 The compounds of 2,4-bis-(N,N-dialkylamino)-6-(O,O’-dibuthyldithiophosphate-S-yl)-s -1,3,5-triazine were synthesized.The tribological properties of these compounds as additives in rapeseed oil (RSO) were examined with four-ball machine.The results show that all additives greatly increase the load-carrying capacity of the base oil,and also increase friction-reducing and antiwear properties of RSO.The worn surfaces of the steel ball lubricated with the additive-containing base oil were analyzed by means of X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy(SEM).The results show that a S,P-containing inorganic and P-containing organic film is formed on the steel ball surface during tribological process.更多还原
