Abstract

This study aims to evaluate the tribological properties of two protic ionic liquids (PILs) under different tribological conditions as a sustainable alternative for mineral oil-based neat lubricants. The synthesis of PILs in this study uses a relatively simple and less expensive method. The Fourier transform infrared (FTIR) spectroscopy results help validate the synthesised PILs’ formation. Further, their physicochemical and tribological properties were investigated. The PILs as neat lubricants were tested on a ball-on-plate reciprocating tribometer using bearing steel–bearing steel and bearing steel–aluminium alloy friction pairs at 30 °C and 80 °C. The results show that the investigated PILs significantly reduced the coefficient of friction and wear. The dodecylamine-based PILs performed better in friction and wear reduction than the other investigated lubricants. The formation of the adsorption layer on the friction pairs was assumed to be the dominant friction and wear reduction mechanism.

氨基质子离子液体作为钢-钢和钢-铝接触纯润滑剂的润湿性、流变性和摩擦学性能研究

本研究旨在评估两种质子离子液体(pil)作为矿物油基纯润滑剂的可持续替代品在不同摩擦学条件下的摩擦学性能。本研究采用了一种相对简单且成本较低的方法来合成pil。傅里叶变换红外光谱(FTIR)结果有助于验证合成的pil的形成。进一步研究了其物理化学和摩擦学性能。在30°C和80°C条件下，用轴承钢-轴承钢和轴承钢-铝合金摩擦副在球-板往复摩擦计上测试了作为纯润滑剂的pil。结果表明，所研究的PILs显著降低了摩擦磨损系数。十二胺基pil在减少摩擦和磨损方面比其他所研究的润滑剂表现更好。在摩擦副上形成吸附层是主要的摩擦减磨机理。
