This research focused on preparing AlCrSi/a-C:H nano-multilayer films, systematically investigating their tribological behavior in rolling-sliding contacts. Notably, the film achieved superlubricity under a wide range of slide-to-roll ratios (0–100 %) in nitrogen. The superlubricious film largely reduces interfacial adhesion and shear forces, which contribute to both pure sliding and pure rolling friction. Detailed characterization revealed that an ultra-thin transfer film is the key for achieving superlubricity in rolling-sliding contacts.
