| description | With the rapid advancement of high-voltage engineering, meeting the increasingly demanding requirements for electrical contact materials in traditional high-voltage direct current (DC) contactors has become a challenge. Graphene has shown promise as an additive for enhancing the mechanical properties and functionality of reinforced polymers and ceramic matrix composites. However, its direct application in metal matrices remains challenging due to difficulties in achieving favorable wetting within carbon/metal systems, leading to inadequate dispersion of graphene and aggregation issues. In this study, we present an in situ growth method of graphene on copper powder. Employing a powder metallurgy approach, we have successfully established a continuous three-dimensional graphene interconnection network within the copper matrix. The resulting composite material not only exhibits elevated mechanical strength but also demonstrates slight improvements in conductivity and thermal conductivity. Notably, the prepared composite materials demonstrate exceptional performance in terms of friction resistance, oxidation resistance, and corrosion resistance, which are particularly suitable for applications such as electrical contact materials. These findings offer new possibilities for replacing traditional electrical contact materials in high-voltage DC contactors. |
