Abstract: |
Due to the strong corrosive nature of seawater, the marine equipment, particularly metal components, faces severe corrosion challenges. In recent years, numerous researchers have been dedicated to extending the service life of metal components in marine environments, making significant progress in improving corrosion resistance and corrosion fatigue performance. The work aims to review the Chinese and international research related to corrosion damage and corrosion fatigue of metal components in marine environments, and delve into the shortcomings of corrosion fatigue research and future development directions. The discussion begins by examining the factors affecting metal corrosion damage and corrosion fatigue, focusing on environmental factors and surface quality of components. Environmental factors (such as dissolved oxygen concentration, temperature, salinity, pH, and load) can cause varying degrees of corrosion and corrosion fatigue damage to metal components. Additionally, the cyclic loads imposed by wave fluctuations or self-induced motion further exacerbate corrosion fatigue. Surface quality (such as surface roughness, residual stress, and microstructure) is crucial to the surface performance of metal components. Good surface quality (e.g. high residual compressive stress and low surface roughness) can not only mitigate corrosion damage but also enhance corrosion fatigue performance. Since it is nearly impossible to eliminate environmental corrosive factors, researchers have explored methods to improve the surface quality of metal components to enhance their corrosion resistance and corrosion fatigue performance. Studies have shown that surface modification techniques are effective means of improving the corrosion resistance and corrosion fatigue performance of metal components. The work aims to summarize the characteristics of various surface modification techniques (including surface coatings, mechanical shot peening, laser shock peening, and ultrasonic surface modification) in isolating corrosive environments and altering surface properties. Coatings can effectively enhance the corrosion resistance of metal components by isolating the metal surface from the corrosive medium. However, under cyclic loading, coatings are prone to delamination. Strain hardening techniques improve corrosion fatigue performance by enhancing the surface properties of metal components, but since the metal components are in direct contact with the corrosive environment, the effectiveness of strain hardening in enhancing corrosion resistance is limited. In response, a new method of composite modification involving surface coatings and strain hardening in introduced, applying laser shock peening to coated components or applying surface coatings to components that have already undergone laser shock peening. The former can reduce or even eliminate the residual tensile stress in the coating through laser shock, while the latter can increase the interfacial adhesion of the coating. These methods combine the advantages of surface coatings and surface strain hardening to enhance the corrosion resistance and corrosion fatigue performance of components, providing new approaches for combating corrosion fatigue in metal components used in marine environments. At present, the research on the corrosion resistance and corrosion fatigue performance of metal components is continuously advancing. However, accurately identifying the mechanisms of corrosion failure remains a challenge due to the complex and diverse factors affecting corrosion damage and corrosion fatigue. Existing modification methods have shown some effectiveness in extending the corrosion fatigue life of metal components, but the problem has not yet been completely resolved. Looking forward, addressing the issues of corrosion damage and corrosion fatigue failure in metal components will require focused research on the mechanisms of corrosion damage and corrosion fatigue failure. |
