Abstract
The different solution-processed concentrations of graphene solid lubricant (0 – 30 mg/mL) were applied on the surface of copper/stainless steel 304 L composite foils. A variable trend of rolling force occurs, with a first falling and then rising trend and the lowest rolling force was obtained at 25 mg/mL for 3.82 kN. Besides, the height of ridges and aspect ratio were improved with an increased solution-processed concentration. On the valley surfaces, the GNPs filled up the cracks, flattened the grooves and eliminated the micro scratches. This indicates the self-repairing and self-polishing mechanisms of GNPs in the micro rolling process. The sliding and exfoliation of GNPs also contributed to the reduced roughness and improved quality of the sample surfaces.
