| Abstract: |
| The work aims to summarize the relevant research on DSS Marine environment adaptation and point out that in addition to the element composition, the microstructure grain size, the second phase and the ratio of ferrite and austenite, sea temperature, carrier concentration in passivated film and other factors play a more critical role in the corrosion resistance of duplex stainless steel. At the same time, the research on selective corrosion in ferrite and austenite structures which are the main components of DSS is analyzed. It is pointed out that selective corrosion is closely related to electrode potential and medium environment.Finally, the shortcomings of the corrosion research of DSS under different factors are pointed out and the further research directions are needed. |
