Abstract
Due to existing the synergistic effect, the novel zinc borate/MoS2 nanocomposites (ZB/MoS2) were successfully fabricated by a liquid phase-based sonication. Subsequently, they were employed as additive to investigate tribological properties in grease. The structure, composition and morphology of the ZB/MoS2 as well as ZB/MoS2-based grease were determined by a series of characterizations, such as XRD, FTIR, Raman, TEM, SEM and EDX, indicating that the ZB nanoparticles were uniformly anchored on the surface of MoS2 nanosheets. The tribological properties of ZB/MoS2 nanocomposites were extensively studied through a four-ball testing machine. The experimental results indicated that the average friction coefficient and average wear scar diameter of the ZB/MoS2-based grease decreased by about 28.2% and 23.1%, and furthermore the extreme pressure performance increased by about 23.1% comparing to base grease. Finally, the antiwear mechanism was proposed by detecting worn surface.
