Abstract The current investigation is aimed at evaluating and comparing the tribological performance of Cu-based composites containing a fixed amount standalone 2D layered materials (MoS2 and reduced graphene oxide; rGO) and their hybrid rGO-MoS2. The study also intends to explore the role of electronic work function of the 2D reinforcements in affecting the tribological performance of the composites. Results indicate that friction and antiwear properties of composites are governed by inherent lubrication properties of reinforcement fillers, interfacial interaction of cooper matrix with reinforcement phase, and the electronic work function (EWF). The study is expected to open up new directions in developing hybrid 2D materials as potential solid lubricants for fabricating metal based self-lubricating composites with improved tribological performance.

含纳米结构二维材料的铜基复合材料及其杂化材料的摩擦学性能评价

摘要 目前的研究旨在评估和比较含有固定量独立二维层状材料(MoS2 和还原氧化石墨烯;rGO)及其混合 rGO-MoS2 的铜基复合材料的摩擦学性能。该研究还打算探索二维增强材料的电子功函数在影响复合材料摩擦学性能中的作用。结果表明,复合材料的摩擦和抗磨性能受增强填料的固有润滑性能、铜基体与增强相的界面相互作用以及电子功函数 (EWF) 的控制。
