Abstract: Ships and marine engineering equipment are highly prone to corrosion under the interaction of multiple factors in the marine environment such as humidity, temperature, salinity, wind and waves, and radiation, which leads to sharp degradation of structural performance, significant shortening of service life, and notable increase in operation and maintenance costs. High-performance anticorrosive coatings, as an important line of defense against marine erosion, play a significant role in ensuring the safety and reliability of equipment operations. In this paper, focusing on the efficient anticorrosive requirements of ships and marine engineering equipment, and combining the corrosion characteristics and mechanisms of the marine environment, the preparation technologies and anticorrosive mechanisms of organic and inorganic anti-corrosion coatings, and the design principles and construction methods of intelligent anticorrosive coatings are discussed, providing theoretical basis and technical support for the corrosion protection technology of ships and marine engineering equipment. Furthermore, the development prospects of marineanticorrosive coating materials in multi-functional applications, data-driven design and intelligent monitoring technologies are prospected.
