▎ 摘　　要

NOVELTY - Graphene-modified aluminum-based composite plate comprises aluminum alloy, ceramic, alkyl magnesium solution and graphene in a mass ratio of 4500-5000:10-50:1000:1. The particle size of the ceramic is 0.05-50 mum. The particle size of the aluminum alloy is 10-100 mum, where the ceramic includes silicon carbide, boron carbide (B4C), titanium carbide or titanium diboride. USE - Used as graphene-modified aluminum-based composite plate. ADVANTAGE - The composite plate has high tensile strength of 512 MPa, high yield strength of 407 MPa, and corrosion rate of 0.9 g/m2/day. The method is simple and efficient. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for the preparation of the graphene-modified aluminum-based composite plate.
