Abstract

Friction and lubrication of components in mechanical transmission systems are crucial to their transmission efficiency. As for the extreme conditions, the performance of traditional liquid lubricants would be degraded, which causes significant harm to the safe and reliable operation of equipment. Therefore, the development of a high-efficiency composite lubricant is particularly important. In this study, MXene@Triethanolamine borate nanocomposite were prepared via the ultrasonic intercalation method. Furthermore, the composites were characterized by scanning electron microscopy, X-ray diffraction, and Fourier transform infrared spectroscopy. The tribological properties of intercalated MXene@TB in the BMIMPF6 ionic liquid were evaluated under current using a ball-on-disk tribometer. The average friction coefficient of lubricant with 0.3% intercalated MXene@TB-1 was reduced by 9.8%, and its wear volume was also decreased by 36.1%. Additionally, the application of current can enhance the tribological performance of lubricant. Specifically, the wear volume of int-MXene@TB-2 was decreased by 52% due to the current-induced ion migration and lubricating film repair. Moreover, the application of current promotes the movement of nanoparticles within the ionic liquid, minimizing aggregation and further enhancing the formation of the lubrication film. The lubricant nanocomposite with high-efficiency friction reduction and anti-wear properties can be further applied in current-carrying friction field.

插层MXene@Triethanolamine硼酸盐纳米复合材料作为润滑油添加剂的智能电流控制行为

机械传动系统中部件的摩擦和润滑对其传动效率至关重要。在极端条件下，传统液体润滑剂的性能会下降，对设备的安全可靠运行造成重大危害。因此，开发一种高效的复合润滑剂就显得尤为重要。本研究采用超声插层法制备了MXene@Triethanolamine硼酸盐纳米复合材料。利用扫描电镜、x射线衍射和傅里叶变换红外光谱对复合材料进行了表征。利用球盘式摩擦计测试了嵌入MXene@TB在BMIMPF6离子液体中的摩擦学性能。掺入0.3% MXene@TB-1的润滑油平均摩擦系数降低了9.8%，磨损量降低了36.1%。此外，电流的施加可以提高润滑油的摩擦学性能。其中，由于电流诱导离子迁移和润滑膜修复，int-MXene@TB-2的磨损体积减小了52%。此外，电流的施加促进了离子液体内纳米颗粒的运动，减少了聚集，进一步促进了润滑膜的形成。该润滑纳米复合材料具有高效减摩抗磨性能，可进一步应用于载流摩擦领域。图形抽象
