Abstract: Stainless steel was widely used in industrial production with its excellent oxidation resistance, corrosion resistance and other properties. But in the marine environment, the stainless steel material was affected by the seawater environment easily and the corrosion resistant properties reduced. It was analyzed that the corrosion mechanism of stainless steel in seawater, and the influence factors of influence in seawater corrosion of stainless steel were discussed from the angle of content, salinity, dissolved oxygen and water flow rate, microbial. Finally the research situation of the current stainless steel anti-corrosion technology was discussed.

摘要： 不锈钢因具有优良的抗氧化、耐腐蚀等特性被广泛地应用于工业生产中。但是,不锈钢材料在海洋环境中容易受到海水的影响而降低其耐腐蚀特性。分析了不锈钢在海水中的腐蚀机理,并从溶解氧浓度、海水pH、海水流速、微生物等角度讨论了影响不锈钢在海水中腐蚀的因素,探讨了当前不锈钢防腐技术的研究情况。
