The present study investigated the tribocorrosion behavior and mechanisms of nickel-aluminum bronze alloys in artificial seawater, offering theoretical support for the advancement and application of marine’s equipment. The study examined the alloy’s tribological performance, electrochemical properties, and the synergistic effect of corrosion and wear using a reciprocating wear tester. Wear scars were analyzed using scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), and X-ray photoelectron spectroscopy (XPS). The results demonstrated a positive synergistic effect between corrosion and wear, with this effect being more significant at lower loads. Of the factors influencing the total tribocorrosion rate, the most critical was the change in wear rate caused by corrosion. Damage analysis revealed that wear samples under cathodic protection suffered severe abrasive wear, while unprotected wear samples developed tribocorrosion products, mainly consisting of Cu₂O, CuO and Al₂O₃, which accelerated the damage of NAB alloy. Corrosive wear was identified as the primary wear mechanism in these conditions. The amount of remained surface tribocorrosion products was largest under medium load wear test (7.6 N).
