  • Method for reinforcing metal material by means of graphene
    Patent number: 10926331
    Abstract: A method of reinforcing a metallic material includes adding graphene to an alcohol solution; subjecting the alcohol solution containing graphene to sonication; mixing a metal powder with the alcohol solution containing graphene; milling the metal powder and alcohol solution containing graphene mixture; drying the metal powder and alcohol solution containing graphene mixture to form a composite powder; subjecting the composite powder to a densification process followed by a hot isostatic pressing treatment to form a composite material; and molding the composite material by hot extrusion.
    Type: Grant
    Filed: September 30, 2016
    Date of Patent: February 23, 2021
    Assignee: AVIC BEIJING INSTITUTE OF AERONAUTICAL MATERIALS
    Inventors: Shaojiu Yan, Cheng Yang, Qihu Hong, Dabo Liu, Shenglong Dai, Zuoming Lin
  • Preparation method of graphene/metal composite board
    Patent number: 9878528
    Abstract: A method for preparing a graphene/metal composite sheet includes adding polyvinyl alcohol into distilled water and heat to about 100° C. under stirring to prepare a polyvinyl alcohol solution; dispersing graphene in distilled water using ultrasonication to prepare a graphene solution; mixing the polyvinyl alcohol solution and the graphene solution to form a graphene/polyvinyl alcohol mixed slurry; after a metal sheet is subjected to a surface activation treatment, coating the graphene/polyvinyl alcohol mixed slurry onto the metal sheet at both upper and lower surfaces; vacuum sintering to remove the polyvinyl alcohol in the surface coating to obtain a graphene/metal plate; overlaying at least two graphene/metal plates and bonding them together via hot isostatic pressing to form multilayer graphene/metal plates; and hot rolling the bonded multilayer graphene/metal plates to form the graphene/metal composite sheet.
