This study provides an in-depth analysis of the corrosion resistance of metal products in marine environments, and specifically examines the effectiveness of Type 12S-1 anticorrosive coating in protecting metals in marine environments. The corrosion-resistant behavior of different metal materials under marine conditions is discussed in depth, and a theoretical basis for subsequent simulation experiments is established through electrochemical corrosion theory. This paper focuses on the corrosion performance of clutch air spring airways under different metal materials and conditions of coated or uncoated Type 12S-1 anticorrosive coating, and salt spray tests are used to evaluate and compare the corrosion protection effectiveness of various treatments. The results proved that the 17-4pH material still showed excellent corrosion resistance without coating, and the application of Type 12S-1 anticorrosive coating could enhance the corrosion resistance of the metal to a certain extent. This study not only provides a solid theoretical and empirical foundation for metal anti-corrosion technology in the marine environment, but also provides an important guidance for the optimization of anti-corrosion strategies for ship materials, and provides practical references and directions for the development of related industries.
