| This paper summarizes the types of high temperature marine corrosion environment and the corrosion failure mechanism of various alloys in different environments. The diffusion behavior of main elements in Fe, Ti and Ni based alloys at high temperature and the interaction with corrosive ions are investigated. The possibility of chemical / electrochemical reaction is discussed from the perspectives of salt spray corrosion and molten hot corrosion. Based on the formation process of composite oxide film in the process of oxidation and corrosion, the reaction mechanism of oxide film with corrosive ions and impurity gas is summarized, and the types of protective oxide film and non-protective oxide film are defined. From the perspective of alloying, the key role of Cr, Al and other elements in improving the anti-corrosion performance is revealed, and the potential application value of material calculation in high-temperature marine environment is pointed out. Finally, the coating protection means and material system in high-temperature marine environment are summarized, in which the structural stability and interface reaction are the focus of coating material research. In the future research direction, this paper points out that we should focus on the interaction of active elements and the formation mechanism of passive film in the corrosion process, and screen effective protective elements. Using oxidation, salt spray and other corrosion conditions, the coating is optimized based on the structure-activity relationship, and a systematic marine high-temperature coating protection scheme is formed. As a new system, the application of high entropy alloy coating in high temperature protection has research value. |
