Abstract
Purpose
This study aims to prepare thymol-based deep eutectic solvents (DESs) and use them as lubricates for friction and wear tests to simulate the wear conditions of hybrid bearings.
Design/methodology/approach
Through the characterization and analysis of the morphology of wear scars and the elemental composition of friction films, the tribological behavior and wear mechanism of sample materials as lubricants were investigated and the anti-wear mechanism of thymol-based DESs was discussed.
Findings
The findings demonstrate that because of the formation of a fluid lubrication film and excellent kinematic viscosity, the lubrication effect of the prepared DES is improved by about 50% compared to the base lubricating oil. The prepared [Ch]Cl-thymol DES has a better anti-friction and lubrication effect than citric-thymol, EG-thymol and urea-thymol DESs, with an average friction coefficient of about 0.04.
Originality/value
In this work, the friction reduction properties of thymol-based DESs were studied as lubricants for the first time, and the lubrication mechanism of sample materials was investigated.
目的本研究旨在制备百里酚基深共晶溶剂(DES),并将其用作润滑剂进行摩擦和磨损试验,以模拟混合轴承的磨损条件。设计/方法/途径通过对磨损疤痕的形态和摩擦膜的元素组成进行表征和分析,研究了作为润滑剂的样品材料的摩擦学行为和磨损机理,并探讨了百里酚基 DES 的抗磨机理。研究结果研究结果表明,由于形成了流体润滑膜和优异的运动粘度,制备的 DES 的润滑效果比基础润滑油提高了约 50%。所制备的[Ch]Cl-胸腺酚 DES 与柠檬-胸腺酚、EG-胸腺酚和脲-胸腺酚 DES 相比具有更好的减摩和润滑效果,平均摩擦系数约为 0.04。
