Macroscopic superlubricity enabled by the tribopair of nc-Ag/MoS2 and hydrogenated graphitic-like carbon films under high contact stress

•The heterogeneous interface paired by nc-Ag/MoS2 and GLC films achieved robust superlubricity at high contact stress for long working duration.•The tribopair achieved COF as low as 0.005 and wear rate at 3.67×10-8 mm3/N·m under a high contact pressure up to 2.33 GPa for 50000 cycles.•High contact stress induced MoS2 to be highly crystallized and well aligned along the sliding interface, along with the graphitization of GLCH film.
