摘要
To develop a potential substitute for sulfurized olefins, a borate ester derivative containing xanthate group (titled BXT) was synthesized and characterized. Meanwhile, its tribological properties in rapeseed oil were evaluated using four-ball tribometer. The results indicate that BXT shows excellent tribological capacity such as load-carrying, friction-reducing and antiwear property. Moreover, the synthesized compound has no noticeable odor, shows little corrosion to copper, and exhibits better thermal stability compared with sulfurized olefins. In order to study the action mechanism of BXT in friction process, analysis of the worn surface was carried out using a three-dimensional non-contact surface profilometer and XPS analyzer.
