摘　　要：In this study,the nanocomposites of MoS_(2) nanoparticles(NPs)grown on carbon nanotubes(MoS_(2)@CNT),graphene(MoS_(2)@Gr),and fullerene C60(MoS_(2)@C60)were synthesized,characterized,and evaluated for potential use as lubricant additives.By using the benefit of the synergistic effect between MoS_(2) and carbon nanomaterials(CNMs),these nanocomposites can be well dispersed in polyalkylene glycol(PAG)base oil and show superior stability compared with pure MoS_(2) NPs.Moreover,the dispersions of MoS_(2)@CNT,MoS_(2)@Gr,and MoS_(2)@C60 added in PAG have noticeably improved friction reducing and antiwear(AW)behaviors at elevated temperature for comparison with that of PAG and PAG containing CNT,Gr,C60,and M0S2 NPs,respectively.The enhanced lubricating properties of these nanocomposites were also elucidated by exploring the tribofilm formed on the disc.
