摘要

为了提高润滑油的性能，本研究采用简单的超声分散法制备了液态金属/离子液体1-己基-3-甲基咪唑六氟磷酸（LM/IL）添加剂。使用四球摩擦计测试了LM/IL的极压性能、抗磨性能和减摩性能。加入0.2 wt% LM后，从1962 N到2884 N， LM/IL的PB值增加了46.9%。在392 N时，LM/IL还表现出优异的抗磨减摩性能。第一原理计算和实验测试结果表明，摩擦引起的化学反应形成了边界润滑膜，显著提高了润滑油的摩擦学性能。

Liquid metal/ionic liquid lubricants: rational design and tribological performance evaluation

To improve the performance of lubricants, a liquid metal/ionic liquid 1-hexyl-3-methylimidazole hexafluorophosphate (LM/IL) additive was prepared in this study using a simple ultrasonic dispersion method. The extreme pressure performance, anti-wear, and friction reduction properties of LM/IL were examined using a four-ball tribo-meter. After incorporating 0.2 wt% LM into IL, the P_B value of LM/IL increased by 46.9% from 1962 N to 2884 N. The LM/IL also exhibited superior anti-wear and friction reduction properties at 392 N. Results of the first principles calculation and experimental tests indicate that the friction induced chemical reactions to form a boundary lubrication film that significantly enhanced the tribological properties of the lubricant.
