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...

Microchannels on metallic substrates are essential parts of microreactors, micro heat exchangers, micro heat sinks, and fuel cell bipolar plates. Because of superior properties, such as good corrosion resistance, excellent thermal conductivity, high strength, excellent ductility and structural stability, composite metal foils are gaining popularity as substrates for microchannels. With the increasing demands of low cost, high efficiency and accuracy, novel micro forming technologies must be capable of creating intricate and precise micro features of microchannels at a low cost. An ultra-thin m...
