| Abstract: |
| In this paper, the main material of marine equipment, the steel is taken as the research object. The research progress on corrosion and protection of structural steels in marine environment is summarized. The corrosion and corrosion mechanism of structural steels under the influence of various factors in the different areas of marine environment are described. The research progress of corrosion resistant structural steels material and typical corrosion resistant low alloy steels used in marine environment at home and abroad are expounded. At present, the corrosion resistance of alloy steel materials is mainly improved by microalloying technology and microstructure control technology. The development of corrosion resistant structural steel in China is relatively backward compared with foreign researches. In addition to the two technologies to improve the corrosion resistance of structural steel materials, traditional corrosion research methods combined with new corrosion research methods based on machine learning technology are used to explore the influence of marine environmental factors, material composition and organizational structure factors on the corrosion rate of structural steel. It is of great significance to study the corrosion mechanism of structural steel, accelerate the development of new corrosion resistant structural steel, and prolong the service life of marine equipment. |
