The coating structure in ML (Ni) exhibited high efficacy in reducing friction at increasing loads, displaying an average CoF after 10,000 revs of < 0.2 at all loads up to 25N (equivalent to ~1.15 GPa; Figure ). This confirmed the performance of the coating ML (Ni) system at the targeted > 1 GPa contact pressures. The coating fails near immediately at 44N (~ 1.39
