Abstract

The invention discloses a preparation method of a graphene oxide coating metal laminated composite material. The method includes: dripping graphene oxide on the surface of a metal sheet, then carryingout vacuum drying treatment to obtain a metal sheet with a graphene oxide coating, then putting the metal sheet with a graphene oxide coating in a spark plasma sintering furnace, and conducting lamination and sintering treatment sequentially, thus obtaining the graphene oxide coating metal laminated composite material. According to the invention, by conducting lamination and sintering treatment on the metal sheet with a graphene oxide coating in a spark plasma sintering furnace sequentially, the graphene oxide coating and the metal sheet can generate a carbide under high temperature and highpressure conditions, so that the graphene oxide coating and the metal sheet can be tightly combined, thus realizing the structural function integration and high densification of the graphene oxide coating metal laminated composite material, and overcoming the defect of complex interface combination of conventional lamellar structure materials.

Description

Background technique [0002] Metal materials are an important material basis for the development of human society, and have been widely used in aerospace, biomedicine, marine ships, chemical engineering and other fields. The application in related fields not only requires high specific strength, high specific modulus, good biocompatibility and other properties, but also hopes for higher development in corrosion resistance. [0003] Graphene or graphene oxide is a new type of carbon material with excellent properties. Graphene or graphene oxide has been reported to have ultrahigh strength, excellent corrosion resistance, and excellent biological properties. Therefore, the application of graphene and its derivatives in the fields of anti-corro...
