Abstract

In this paper, the corrosion behavior of me tal materials, non-me tal materials and composite materials in Marine environment is systematically analyzed. The corrosion characteristics and influencing factors of different material types in Marine environment are discussed. In the section of development and application of corrosion resistant materials, this paper discusses the corrosion resistance improvement of stainless steel materials, including the role of alloying elements, surface treatment technology and coating protection. At the same time, the applications of high performance alloys in Marine engineering, such as nickel-based alloys, titanium alloys and copper alloys, are analyzed. In addition, organic coatings and anti-corrosion coatings are discussed, as well as corrosion resistance of non-me tallic materials such as glass fiber reinforced plastics (FRP), high-performance plastics, and ceramic matrix composites. In the section of the future development trend of corrosion resistant materials, this paper looks forward to the development of nanocomposite coating technology, environmentally friendly corrosion resistant materials, and the application of high-temperature corrosion resistant materials in deep sea oil exploration. The future direction of corrosion resistant materials research is pointed out, including the development of new materials, the study of environmental adaptability and the integration of interdisciplinary technologies. With the continuous emergence of new materials and new technologies, the application prospects of chemical engineering materials in Marine engineering will be broader, and provide more reliable material support for the development and utilization of Marine resources.
