The carboxyl group at the edge of graphene oxide (GO) is an acidic group,which will cause corrosive wear of the metal friction pair during the friction process.In order to reduce the corrosive wear of the carboxyl group,GO and glycerol were introduced to synthesize a type of hydroxylated graphene oxide additives (GOOH) used in waterbased lubricants.Atomic force microscopy (AFM) and scanning electron microscope (SEM) were employed to observe the surface topography of GO before and after modification.Fourier Transform infrared spectroscopy (FTIR) were used to characterize the structure of synthesized additive,and the stability test and copper corrosion test of synthesized additive were also carried out.The tribological properties of GO and GOOH as additives in waterbase lubricants were evaluated using a four ball tester.The morphologies of worn surfaces were investigated by scanning electron microscopy (SEM) and the element composition on the worn surface were studied by energy dispersive spectroscopy (EDS).The results indicate that the synthesized GOOH is as stable as GO in water,but the corrosivity of GOOH is weaker than that of GO.SEM analysis results show that the worn surfaces are more regular and smooth by adding GOOH,and the EDS analysis results indicate that the worn surface has more carbon by adding GOOH than adding GO,showing that GOOH can better adsorb on the surface of friction pairs and play a role of antiwear and frictionreducing.
