摘要

With the growing concern about environmental pollution, vegetable oils have begun to be applied as base oils for environmentally friendly lubricants. Additives containing phosphorus can be used for their excellent antiwear properties and low toxicity. In view of this, a study of a series of phosphate esters as additives in rape seed oil (RSO) was carried out using a four-ball tester. The results indicate that phosphate esters possess very good load-carrying capacity and good antiwear and friction-reducing properties compared with RSO by itself. Surface analysis of the worn balls was carried out using X-ray photoelectron spectroscopy (XPS) and scanning electron microscopy (SEM). The tribological mechanism of the additives is discussed on the basis of the experimental results.
