| 中文摘要: |
| 针对DSS海洋环境自适应相关研究进行了总结，指出除元素组成外，组织晶粒大小、第二相及铁素体和奥氏体两相组织比例变化、海水温度、钝化膜中载流子浓度等相比其他因素对双相不锈钢的点蚀性能更能起到关键性的影响。同时分析了DSS主要组成相铁素体和奥氏体组织发生择性腐蚀相关研究，指出发生选择性腐蚀与电极电位、介质环境有较大关系。最后，指出了DSS在不同因素下的腐蚀研究还存在不足和下一步需要继续深入研究方向。 |
| 英文摘要: |
| 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. |
