NOVELTY - Improving titanium-based composite material performance by oxygen-containing graphene modified dispersion comprises (i)ultrasonically stirring and dispersing the oxygen-containing graphene nanopowder in deionized water to form an oxygen-containing graphene dispersion, heating the oxygen-containing graphene dispersion, adding it drop by drop with a straw modified solvent polyetheramine undergoes a spontaneous reaction to obtain a reduced graphene oxide monomer solution; (ii) placing reduced graphene oxide monomer solution in an ethanol solution for ultrasonic stirring and uniform dispersion, and then slowly adding titanium or titanium alloy powder for constant temperature ultrasonic mechanical stirring to obtain slurry, drying and grinding the slurry to obtain a modified titanium-based powder of reduced graphene oxide monomer; and (iii) performing densification and sintering of the titanium-based powder modified by the reduced graphene oxide monomer and thermal deformation processing. USE - The method is useful for improving titanium-based composite material performance by oxygen-containing graphene modified dispersion. ADVANTAGE - The method enables to improve titanium-based composite material performance by oxygen-containing graphene modified dispersion, which has high boiling point, good thermal stability, proper viscosity, in the ultrasonic mechanical stirring process.
