Two borate ionic liquids 1-Butyl-3-(2-methoxy-2-oxoethyl)-imidazole bis(mandelato)-borate [MABIM][BMB]) and 1,3-Dioctylbenzotriazole bis(mandelato)-borate ([DOBI][BMB]) were synthesised and utilised as the lubricating additives. Their corrosion degrees were measured and the results show that [DOBI][BMB] and [MABIM][BMB] exhibit remarkable anti-corrosion properties ([DOBI][BMB]: 1a, [MABIM][BMB]: 1b). The 4-ball machine was employed to evaluate their tribological properties in 500 N base oil. When [DOBI][BMB] and [MABIM][BMB] were added at the concentration of 3.0 wt%, the friction coefficient of 500 N was reduced by 37.5% and 29.5%. It can be concluded from the results of XPS and SEM that a lubricating film containing iron oxide, B₂O₃ and organic N-containing compounds have formed. And a model is proposed so as to describe the lubricating mechanism.

低腐蚀等级和优异热稳定性硼酸盐离子液体在500 N基础油中的摩擦学性能

两种硼酸盐离子液体 1-Butyl-3-(2-methoxy-2-oxoethyl)-imidazole bis(mandelato)-borate [MABIM][BMB]) 和 1,3-Dioctylbenzotriazole bis(mandelato)-borate ([DOBI] [BMB]) 被合成并用作润滑添加剂。测量了它们的腐蚀程度，结果表明[DOBI][BMB]和[MABIM][BMB]表现出显着的防腐性能（[DOBI][BMB]：1a，[MABIM][BMB]：1b）。使用 4 球机来评估它们在 500 N 基础油中的摩擦学性能。当[DOBI][BMB]和[MABIM][BMB]以3.0 wt%的浓度添加时，500 N的摩擦系数降低了37.5%和29.5%。从 XPS 和 SEM 的结果可以得出结论，含有氧化铁 B ₂ O _{3的润滑膜}并形成有机含氮化合物。并提出了一个模型来描述润滑机理。
