Corrosion and wear of metal materials in marine environment and their complex interactions are the main factors affecting the reliability and efficiency of marine equipments.On the basis of summarizing the phenomena and problems of corrosion and wear of metal materials in marine environment,the research progress and development trend of interaction between corrosion and wear of typical metals in marine environment were analyzed,corrosion and wear problems of stainless steel,titanium alloy and aluminum alloy which are major metal materials for marine environment under different medium were also discussed,the positive interaction and negative interaction mechanism were specially emphasized among metal corrosion and wear in marine environment,as well as the research progress of their interaction,transition and conversion.In the process of conversion of positive and negative interaction between corrosion and wear,from the microcosmic perspective,the multiple transformation of austenite and martensite phases is the main influencing factor.From the macroscopic perspective,dynamic friction factors such as friction coefficient,load and motion form of the material and electrochemical factors such as Cl- concentration,pH value,frequency and applied potential are the two main influencing factors.Various calculation models of the interaction between corrosion and wear were compared and analyzed,and the research progress of using surface technology to improve the corrosion resistance and wear resistance of metal materials were described,it is proposed that the negative interaction mechanism between corrosion and wear of metal materials,the influence mechanism of microorganisms on the interaction between corrosion and wear,the interaction between fretting wear and corrosion,and the accurate quantification of the interaction between corrosion and wear are the future research focuses
