摘要：

A new type of environmentally friendly lubricant additive - a sulphurised rape seed oil additive - was prepared, and the chemical structure characterised using infrared spectroscopy. The tribological properties of the additive in a rape seed base oil were evaluated using a friction tester. The morphologies and tribochemical species of worn surfaces were analysed by means of X-ray photoelectron spectroscopy. The results show that the additive increased the load-carrying capacity and improved the antiwear and friction-reducing properties of the rape seed oil. The inferred lubrication mechanism is that a high-strength adsorption film and a tribochemical reaction film form on rubbing surfaces due to the carrier effect of the long-chain rape seed oil molecules, the high reactivity of sulphur, and their synergism.
