In order to solve the problem of silver-based contacts in low-voltage devices, which were prone to fusion and ablation, leading to insufficient electrical life, a new graphene/silver-based composite contact was prepared by the laser method. A fully covered graphene film was prepared on the surface of commercial AgNi15 contacts by laser cladding technology as a stand-alone coating to resist environmental damage. Theoretical analysis and experimental verification were carried out to obtain the optimal process conditions and corresponding performance data. The results demonstrate that the hardness of graphene/silver composite contact is 104.05 HV, the density is 9.15 g/cm3, and the contact resistance is 0.016 Ω. The new solution protocol and experimental bases have been provided for the fabrication of high-performance low-pressure contacts in this study.
