【摘要】 通过现场腐蚀挂片、室内模拟实验和电化学测量研究了A3钢在富营养化淡水环境中和洁净淡水环境中的腐蚀行为及影响因素。结果表明,在淡水环境中,水体的溶解氧量(DO)是决定A3钢腐蚀速度的重要影响因素,在富营养化的东湖水体中,因溶解氧量(DO)低,A3钢的腐蚀速度反而比洁净的梁子湖水体中要低,此外,富营养化水体中的磷的存在对A3钢起到缓蚀的作用。更多还原

【Abstract】 The corrosion behaviors of A3 steel in eutrophic water and clean water were studied by locale corrosion specimen and experiments in simulant condition. The results show that the dissolve oxygen in the water body was chief factor determined A3 steel’s corrosion rate. The corrosion rate of A3 steel in eutrophic water (the East Lake) is slower than it in fresh water(the Liangzi Lake),furthermore, the element of phosphor in eutrophic water has some inhibiting effect for the corrosion behaviors of A3 steel .更多还原
