NOVELTY - Preparing high-strength and high-plasticity graphene-titanium composite material through interface modification, comprises washing graphene oxide with acid and alkali to remove impurities, depositing iron oxide on the surface of graphene oxide by chemical electrostatic assembly method, and adjusting the concentration of iron ions in the solution to control the thickness of the coating to obtain iron oxide coated graphene oxide, mixing iron oxide coated graphene oxide with titanium powder by powder metallurgy, and adopting the discharge plasma method to sinter and forming to obtain the graphene reinforced titanium matrix composite material. USE - The method is useful for preparing high-strength and high-plasticity graphene-titanium composite material through interface modification. ADVANTAGE - The iron oxide modified layer prepared by the method has controllable thickness and state, and has strong bonding force with the graphene, the powder dispersion process is not easy to fall. In the sintering process, it can effectively inhibit the interface reaction of the graphene/titanium composite material, improve the strength and toughness of graphene and titanium composite material. It can well protect the structure of graphene, and realize the strong plastic graphene in the titanium base body.
