In order to improve the tribological properties of phosphate-bonded coatings，the feasibility of modified carbon fibers in coatings was explored.In this work，graphene oxide (GO) was grafted to carbon fibers (CF) by electrophoretic deposition，and the phosphate ceramic coating was prepared by scraping-thermosetting method.Scanning electron microscopy and Raman spectroscopy were used to determine the surface morphology and molecular structure of CF-GO samples，and the influence of CF-GO content on the tribological properties of coatings was studied by friction testing machine.Results showed that the tribological properties of coatings containing CF-GO were significantly better than those containing untreated CF.With the increase of CF-GO content，the friction coefficient and wear rate of phosphate bonded coatings showed changes that decreased first and then increased.Compared with coatings without CF，the coatings containing 10%(mass fraction) CF-GO exhibited excellent tribological properties，and the corresponding average coefficient of friction and wear rate were reduced by 50%and 38%，respectively.This above indicated that the appropriate amount of CF-GO could improve the tribological properties of its coating，which could provide a good reference for the development and engineering application of new phosphate coatings.
