The effects of sulfur type additives T321 and phosphorous type additives P120 on the EP and AW abilities of rapeseed oil were investigated by a four-ball testing machine using the rapeseed oil as base oil.The effect of T321 mixed with P120 on the tribochemical performance of the rapeseed oil was studied.The result shows that the load carrying,extreme pressure and abrasion capacities of lubricant film can be improved by adding T321 and P120 as additives in rapeseed oil, respectively. The SEDX analysis on the surface of steel balls reveals that tribochemical reactions occur during the friction process, the barrier lubricating film is formed containing triglyceride and the additives can improve the anti-wear ability and load-carrying capacity.
