Abstract

In this study, SAE-0W20 engine oil was mixed with graphene and fullerene nanoparticles. The goal of this study was to evaluate and compare the effects of different carbon nanoparticles on the thermal, rheological, and tribological properties of engine oil, such as thermal degradation, viscosity, friction, and wear. Using a two-step process, graphene and fullerene nanostructures were dispersed in low-viscosity SAE-0W20 engine oil at a concentration of 0.05 wt.%. The friction and wear characteristics were evaluated in a customized cylindrical block-on-ring tribology test according to the ASTM G77 standard. Graphene and fullerene nanoparticles protect contact surfaces by forming a very thin protective film between moving mechanical parts thus resulting in wear and friction reduction. The results showed graphene nanoparticles have improved significantly the tribological performance of SAE-0W20 engine oil.

石墨烯和富勒烯纳米颗粒作为润滑油添加剂的性能和摩擦学评价

在这项研究中，SAE-0W20发动机油与石墨烯和富勒烯纳米颗粒混合。这项研究的目的是评估和比较不同的碳纳米颗粒对发动机油的热、流变和摩擦学性能的影响，如热降解、粘度、摩擦和磨损。采用两步法，石墨烯和富勒烯纳米结构以0.05 wt.%的浓度分散在低粘度SAE-0W20机油中。根据ASTM G77标准，在定制的圆柱形块环摩擦学测试中评估摩擦和磨损特性。石墨烯和富勒烯纳米颗粒通过在运动机械部件之间形成非常薄的保护膜来保护接触面，从而减少磨损和摩擦。结果表明，石墨烯纳米颗粒显著改善了SAE-0W20发动机油的摩擦学性能。

期刊介绍： The Journal of Engineering Tribology publishes high-quality, peer-reviewed papers from academia and industry worldwide on the engineering science associated with tribology and its applications. "I am proud to say that I have been part of the tribology research community for almost 20 years. That community has always seemed to me to be highly active, progressive, and closely knit. The conferences are well attended and are characterised by a warmth and friendliness that transcends national boundaries. I see Part J as being an important part of that community, giving us an outlet to publish and promote our scholarly activities. I very much look forward to my term of office as editor of your Journal. I hope you will continue to submit papers, help out with reviewing, and most importantly to read and talk about the work you will find there."
