Abstract | The g-C3N4/Cu nanocomposite was prepared by in situ reduction of Cu2+ adsorbed on the surface defects of g-C3N4, and its tribological properties as an additive were investigated in base oil. Cu nanoparticles can be well distributed on g-C3N4 sheets with an average diameter of 20 nm as revealed by X-ray diffraction patterns and transmission electron microscopic analysis. The tribological properties were determined on an UMT-2 ball-on-disk friction and wear tester. The results indicated that the g-C3N4 and Cu nanoparticles as additives were able to effectively reduce both the friction and wear of sliding pairs in base oil. Moreover, the base oil with g-C3N4/Cu exhibited the best lubricating behavior with the lowest friction coefficient and wear rate compared to g-C3N4 or Cu nanoparticles as additives. Based on our characterization of the wear scars by scanning electron microscopy, a surface mapping profiler, and an energy-dispersive spectrometer, the synergistic lubrication mechanism of g-C3N4 and Cu nanoparticles were also proposed. |
