▎ 摘　　要

NOVELTY - Preparing high-toughness layered titanium-based composite material comprises (i) adding graphene oxide and silicon powder into ethanol, ultrasonically dispersing for 0.5-1 hour, adding aluminum nitrate, stirring uniformly to obtain mixed solution, placing titanium foil into mixed acid solution, washing for 10 seconds, orderly using clean water and ethanol, cleaning, drying, where mass ratio of silicon powder to graphene oxide is 1-3:1, and mixed acid solution comprises hydrofluoric acid, nitric acid and water at volume ratio of 1:3:8; (ii) fixing plate spacing and deposition voltage of cathode and anode for electrophoretic deposition, depositing graphene oxide and silicon powder on titanium foil of cathode at same time, obtaining titanium foil with surface co-deposited graphene oxide-silicon coating, and (iii) stacking titanium foil of surface co-deposition graphene oxide-silicon coating layer along same direction, and sintering under vacuum condition. USE - The method is useful for preparing layered titanium-based composite material. ADVANTAGE - The method: improves the deposition efficiency of graphene oxide and silicon on the titanium foil, exhibits high strength while retaining higher plasticity, and ensures layered titanium-based composite material with high toughness characteristics.
