Electrical contact materials are a key core component of switching appliances. However, the arc-resistance, electrical conductivity and tribological properties of traditional contact materials should be improved for the electrical equipment in the new era. This work proposes a strategy to prepare a novel graphene/silver-based contact material by laser process. Nanosecond laser is applied to grow the graphene film on the surface of commercial AgSnO2 contacts. The optimal process conditions: the laser power is 4.8 W, scanning speed is 5 mm/s, and scanning times is 20. The resistance of graphene/silver-based contact is 0.1 m?, 53.7% better than that of the original contact The oxidation resistance is only 0.12%. The graphene/silver-based contact provides new perspective to produce high-end electrical contact materials.
