| 摘 要： | 对碳钢在不同pH值的4%(质量分数)NaCl溶液中进行浸渍干湿复合循环实验的锈层进行IR分析,确定pH值在3~5范围内腐蚀产物相似,包括-γFeOOH,-αFeOOH,Fe3O4和少量β-FeOOH;通过测定铁锈的质量得出腐蚀速度随pH值增大而减小;认为铁溶解为Fe2+是整个腐蚀过程的速控步骤。

| Abstract: | Carbon steal corrosion products were analyzed by IR.Corrosion test of immersion-dry-wet combined cycles in the 4%NaCl solution with acid.Corrosion products were resemblant in differed pH(3~5)and confirmed to consist of γ-FeOOH,α-FeOOH,Fe_3O_4 and a few β-FeOOH. Corrosion rate decreased while pH increased by measuring rust weight,and the dominated step of corrosion rate is the process from Fe to Fe~(2+). |
