<p>The tribocorrosion behavior of titanium alloys in seawater and simulated seawater environments, such as 3.5% NaCl solutions, poses significant challenges for material science and marine engineering. These alloys are widely employed in marine applications due to their exceptional mechanical properties and corrosion resistance. However, under specific conditions, the synergistic interaction of mechanical wear and electrochemical corrosion can severely degrade their performance. This review provides a comprehensive analysis of recent advances in understanding the tribocorrosion mechanisms of titanium alloys, emphasizing the interplay between sliding wear, erosion, and corrosion. Key factors influencing tribocorrosion, including chloride-induced pitting, crevice corrosion, and environmental parameters such as salinity, pH, and dissolved oxygen, are critically examined. The role of alloying elements in enhancing corrosion and wear resistance is also discussed, highlighting strategies to mitigate degradation. Furthermore, the impact of surface texture on tribocorrosion processes is explored, alongside an evaluation of protective coatings as a viable solution. Various coating technologies are compared in terms of their thickness, surface roughness, and effectiveness in reducing material degradation. Besides, this paper reviews experimental case studies and recent breakthroughs, identifying persistent challenges and innovative solutions in the field. Future research directions are proposed, emphasizing the development of advanced nanostructured coatings, improved testing methodologies, and the integration of artificial intelligence and machine learning for predictive modeling of tribocorrosion behavior. By advancing these strategies, the goal is to design more durable and efficient materials, thereby extending the service life and performance of titanium alloys in demanding marine environments.</p>
