- Abstract
In order to improve the performance of electrical equipment, it is urgent to develop new high performance contact materials for electric power system. A novel preparation method of graphene/copper composite contacts was presented in this paper. The Ni-Cu alloy transition layer was prepared on the surface of copper (mass fraction was 0. 999) by plasma-assisted processing. On such a transition layer, the graphene surface film was prepared by a high-powered continuous-wave laser in situ, covering the surface of copper as an independent coating to resist the damage of contact material. The plasma-assisted processing and laser processing processes of graphene composite contact materials were explored. The results show that the graphene/copperbased contact materials have excellent electrical characteristics, the resistance is similar to red copper, hardness is 1. 8 times that of red copper, friction coefficient is only 0. 06. This work can provide a new solution and a new material system for electrical materials.
