石墨烯/LaF3的制备及其作为水基润滑剂的摩擦学性能研究

Synthesis, Structure and Tribological Properties of Graphene/LaF3 Composites as Water-Based Lubricant Additives

  • 摘要: 本文中采用简单的液相化学反应和水热还原过程,成功制备了还原氧化石墨烯纳米片和氟化镧复合材料(rGO/LaF3). 通过SRV-1微动摩擦试验机测试了系列样品作为水润滑添加剂时的摩擦学性能. 结果显示:当rGO和LaF3的比值为2∶1时,具有最低摩擦系数0.335;当比值为1∶1时,磨损体积最小;相比纯水,添加rGO/LaF3复合材料(质量分数0.1%)后表现出了一定的减摩和抗磨作用,其中抗磨效果比较明显.

     

    Abstract: The composites of reduced graphene oxide/lanthanum fluoride (rGO/LaF3) have been successfully synthesized through a simple strategy combining liquid phase chemical reaction and hydrothermal process. The tribological properties of series samples as water-based lubricant additives were evaluated by the friction and wear tests, which were carried out on an Optimol SRV-I oscillating reciprocating friction and wear tester. The profile of the wear scar and the volume of wear track were determined by a three-dimensional (3D) surface profiler. The results indicated that the introduction of rGO/LaF3 (weight fraction 0.1%) into the pure water could achieve the goal of reducing friction and wear, which was better than the single rGO.
