用电化学法和失重法测定了低碳钢长期浸泡的腐蚀速率。结果表明,电化学方法的应用产生了错误的值。主要原因是内锈层长期浸泡后产生的β-FeOOH具有较高的电化学活性,影响显著。在电化学测试中,即使很小的极化也会使β-FeOOH参与阴极反应,从而导致对腐蚀速率的高估。为了证实这一点,研究了在曝气和脱氧条件下的电化学行为,考察了锈层对还原反应的影响。经校正后,电化学测量结果与失重量吻合。
Corrosion rates of mild steel for long-term immersion were estimated by electrochemical and weight-loss methods. The results showed that application of electrochemical methods yielded erroneous values. The main reason was that, β-FeOOH, produced after long-term immersion with high electrochemical activity in the inner rust layer, exerted significant influence. In electrochemical tests, even small polarization can make β-FeOOH participate in cathodic reaction, which leads to overestimating corrosion rate. In order to confirm it, electrochemical behaviour was studied in aerated and deaerated conditions to investigate the effect of rust layers on reduction reaction. After calibration, the electrochemical measurement result was coincided with the weight loss.
