▎ 摘　　要

NOVELTY - The preparation method of graphene-based steel alloy involves selecting steel metal substrate and then washing, carrying out surface activation process and then pretreating, performing nickel plating process and then carrying out copper plating process, washing using water and then drying at high-temperature, performing chemical vapor deposition process, and cooling. USE - The method is useful for preparation of graphene-based steel alloy (claimed). ADVANTAGE - The method enables preparation of graphene-based steel alloy with excellent corrosion resistance and thermal conductivity.
