Research Progress on Tribological Properties of Motion Pair Materials in Sea Environment

With the further development of abundant marine resources, the friction and wear problems of marine mechanical equipment motion pairs have been paid more and more attention by researchers. The research status of main materials of motion pairs, including metal, ceramic and polymer in marine environment is summarized, the influencing factors of tribological properties of motion pair materials under marine conditions are analyzed, and the research progress of deep-sea tribology testing equipment is discussed, which can provide support for the selection and application of motion pairs of marine mechanical equipment.
