Abstract

As an oil-based superlubricity material on steel surfaces, 1,3-diketone fluid is promising for the friction reduction of mechanical devices. However, the unsaturation of its molecular structure would potentially cause the oxidation problem in industrial applications. In this study, the oxidation mechanism of diketone fluid 1-(4-ethyl phenyl) nonane-1,3-dione (EPND) was discovered through the accelerated oxidation experiment in an oven. By doping butylated hydroxytoluene (BHT) anti-oxidation additive at an optimal concentration of 0.5%, both the oxidation onset temperature (OOT) and oxidation induction time (OIT) of EPND could be enhanced to a comparable level of 4121 commercial oil, which is a fully-formulated lubricant with a similar viscosity to EPND. Moreover, the friction test verified that the incorporated BHT additive induced negligible influence on the superlubricity performance of EPND. The result of this study is helpful for improving the weakness of the diketone superlubricity system and promotes a further step in its practical applications.

使用丁基羟基甲苯添加剂改善1,3-二酮超润滑液的氧化稳定性

1,3-二酮流体作为一种基于油基的钢表面超润滑材料，在机械设备的减摩方面具有广阔的应用前景。然而，其分子结构的不饱和在工业应用中可能会引起氧化问题。本研究通过烘箱加速氧化实验，发现了二酮流体1-（4-乙基苯基）壬烷-1,3-二酮（EPND）的氧化机理。以0.5%的最佳浓度添加丁基羟基甲苯（BHT）抗氧化添加剂，可将EPND的氧化起始温度（OOT）和氧化诱导时间（OIT）提高到与4121商品油相当的水平，这是一种与EPND粘度相近的全配方润滑油。此外，摩擦试验验证了加入BHT添加剂对EPND超润滑性能的影响可以忽略不计。研究结果有助于改善二酮类超润滑体系的不足，促进其实际应用的进一步发展。

期刊介绍： Lubrication Science is devoted to high-quality research which notably advances fundamental and applied aspects of the science and technology related to lubrication. It publishes research articles, short communications and reviews which demonstrate novelty and cutting edge science in the field, aiming to become a key specialised venue for communicating advances in lubrication research and development. Lubrication is a diverse discipline ranging from lubrication concepts in industrial and automotive engineering, solid-state and gas lubrication, micro & nanolubrication phenomena, to lubrication in biological systems. To investigate these areas the scope of the journal encourages fundamental and application-based studies on: Synthesis, chemistry and the broader development of high-performing and environmentally adapted lubricants and additives. State of the art analytical tools and characterisation of lubricants, lubricated surfaces and interfaces. Solid lubricants, self-lubricating coatings and composites, lubricating nanoparticles. Gas lubrication. Extreme-conditions lubrication. Green-lubrication technology and lubricants. Tribochemistry and tribocorrosion of environment- and lubricant-interface interactions. Modelling of lubrication mechanisms and interface phenomena on different scales: from atomic and molecular to mezzo and structural. Modelling hydrodynamic and thin film lubrication. All lubrication related aspects of nanotribology. Surface-lubricant interface interactions and phenomena: wetting, adhesion and adsorption. Bio-lubrication, bio-lubricants and lubricated biological systems. Other novel and cutting-edge aspects of lubrication in all lubrication regimes.
