907A低合金钢在模拟深海环境中的腐蚀行为及机理
Corrosion Behavior and Mechanism of 907A Low Alloy Steel in Simulated Deep Sea Environment
摘 要
利用自制试验装置,通过静态失重试验、电化学测试,研究了907A低合金钢在模拟1000m深海环境中的腐蚀行为,并对其腐蚀机理进行了分析。结果表明:907A低合金钢在模拟深海环境中的腐蚀速率随浸泡时间的延长而逐渐减小,最终趋于稳定,致密均匀的锈层有效遏制了腐蚀性离子向基体渗透,起到防护作用;腐蚀产物主要以α-FeOOH、γ-FeOOH和Fe3O4为主,随着浸泡时间的延长,γ-FeOOH向α-FeOOH的转化使907A钢的腐蚀速率降低;浸泡初期907A钢表面主要发生点蚀,点蚀萌生于基体与夹杂物界面处,随着浸泡时间的延长,点蚀逐渐转变为均匀腐蚀。

Abstract
The corrosion behavior of 907A low alloy steel in simulated 1 000 m deep sea environment was studied by static weight-lose test and electrochemical test with a self-made test device and its corrosion mechanism was analyzed. The results showed that the corrosion rate of 907A low alloy steel in simulated deep sea environment decreased gradually with the extension of immersion time, and finally tended to be stable. The dense and uniform rust layer effectively restrained the penetration of corrosive ions into the matrix and played a protective role. The main corrosion products were α-FeOOH, γ-FeOOH and Fe3O4. When the immersion time was prolonged, the conversion from γ-FeOOH to α-FeOOH reduced the corrosion rate of 907A steel. At the initial stage of immersion, pitting mainly occurred on the surface of 907A steel, which originated at the interface between matrix and inclusions. With the extension of immersion time, pitting gradually changed into uniform corrosion.
