Abstract

The growing demand for electric vehicles (EVs) has underscored the critical need for efficient lubricants capable of addressing the challenges of the electrified interfaces. This research presents the tribological, thermal, and electrochemical corrosion characteristics of multilayered Ti₃C₂T_x MXene modified by tetradecylphosphonic acid (MXene@TDPA) as antiwear additives. Tribological investigations were performed utilizing an SRV friction tester under the influence of electrification. The results were then compared to those obtained from commercial oil currently used in EVs. The results demonstrate that the lubricant containing the MXene@TDPA additive exhibits superior anti-corrosion characteristics compared to the commercial oil. Notably, the results demonstrate that the MXene@TDPA additive achieves a significant improvement in antiwear properties of up to 77 % at 6 A and 100 °C. Furthermore, the MXene@TDPA additive maintains its lubrication performance across a wide temperature range up to 300 °C without seizure. This work highlights the potential of MXene-based additives to decrease the failure rate of mechanical components in EVs.

电气化条件下，十四烷基膦酸改性Ti3C2Tx MXene提高电动汽车润滑油的抗磨性能

随着电动汽车需求的不断增长，对能够应对电动界面挑战的高效润滑油的需求日益凸显。本文研究了以十四烷基膦酸（MXene@TDPA）为抗磨添加剂改性的多层Ti3C2Tx MXene的摩擦学、热学和电化学腐蚀特性。在通电影响下，利用SRV摩擦试验机进行了摩擦学研究。然后将结果与目前用于电动汽车的商业油的结果进行比较。结果表明，与商品油相比，含有MXene@TDPA添加剂的润滑油具有更好的防腐性能。值得注意的是，结果表明MXene@TDPA添加剂在6 a和100°C下的抗磨性能显著提高了77 %。此外，MXene@TDPA添加剂在高达300°C的宽温度范围内保持其润滑性能而不会发作。这项工作强调了基于mxene的添加剂在降低电动汽车机械部件故障率方面的潜力。

期刊介绍： Tribology is the science of rubbing surfaces and contributes to every facet of our everyday life, from live cell friction to engine lubrication and seismology. As such tribology is truly multidisciplinary and this extraordinary breadth of scientific interest is reflected in the scope of Tribology International. Tribology International seeks to publish original research papers of the highest scientific quality to provide an archival resource for scientists from all backgrounds. Written contributions are invited reporting experimental and modelling studies both in established areas of tribology and emerging fields. Scientific topics include the physics or chemistry of tribo-surfaces, bio-tribology, surface engineering and materials, contact mechanics, nano-tribology, lubricants and hydrodynamic lubrication.
