| 摘 要： | 通过腐蚀失重、电化学测试、锈层分析和微观形貌观察研究了海水压力对不同成分2种低合金钢(X和Y)腐蚀行为的影响.结果表明，X钢更易受到海水压力的影响而被加速腐蚀.深海压力均加速了2种低合金钢的阳极溶解速度；压力对于X钢的氧扩散还原过程影响很小，而海水压力的增加导致Y钢阴极电流密度降低的原因是腐蚀产物直接参与了阴极还原反应...

| Abstract: | In this paper,the effect of hydrostatic pressure on the corrosion behaviors of two steels was investigated by weight loss test,electrochemical measurements,rust layer analysis and morphology observation in natural seawater environment with high-pressure in lab.The results showed that X steel was inclined to being corroded.With the increase of hydrostatic pressure,the corrosion resistance of two steels were deteriorated,which were attributable to the increase of the anodic reaction rate. Hydrostatic pressure... |
