Molybdenum disulfide (MoS₂) is a ubiquitous space lubricant, yet susceptible to degradation by atomic oxygen (AO) in low Earth orbit, impacting material durability. Here, we employ structural optimization to present a series of MoS₂/metal nano-multilayer films by fine-tuning sputtering parameters. Our approach, bolstered by theoretical calculations and experiments, elucidates the dynamic behaviors of various metals on MoS₂ surfaces. MoS₂ in combination with Ti, W, or Pb tends to assume a layered structure, while Ag prefers agglomeration within the film. This precise nano-multilayer architecture, comprising alternating highly oriented MoS₂ and metal layers, effectively restricts oxidation depth less than 35 nm, surpassing previous space lubricants. Intriguingly, metal oxide nanoparticles formed during AO irradiation further reduce friction, enabling robust superlubricity (~0.008). This achievement is facilitated by numerous incommensurate nano-contacts between highly oriented MoS₂ and oxide nanoparticles. Our findings provide invaluable insights into interface design, promising durable and irradiation-resistant lubricating films for space applications.
