摘　　要：由于富营养化会导致淡水水体环境发生重大改变,从而使金属在其中的腐蚀行为更加复杂。目前,国内外对金属在富营养化淡水水体中的腐蚀行为与规律的研究比较少。因此,开展这方面的研究工作具有非常重要的意义。文中将通过电化学方法研究A3钢在富营养化淡水环境中的腐蚀行为,并着重研究温度、pH值、含氧量等因素对A3钢电化学腐蚀行为的影响。The environment of fresh water has been changed greatly because of eutrophication, which made the corrosion behavior of metal in this water become more and more complex. Presently, the study on the corrosion behaviors and mechanism of metals in eutrophic fresh water was very few; therefore, we considered the research on this field was a very meaning work. In this paper, the corrosion behavior of A3 Steel in eutrophic fresh water was studied by electrochemical methods. The influence of temperature, value of pH and dissolving oxygen content on the electrochemical corrosion behavior of A3 steel were investigated.
