讨论了碳钢材料在海水环境中的腐蚀速率随时间的变化情况，总结了碳钢在海水中不同暴露阶段的腐蚀和生物污损特性。结果显示，碳钢在海水中的腐蚀速度随时间延长而下降，暴露1～2年后腐蚀速率变化不显著，其腐蚀过程可分为腐蚀过程控制阶段、氧扩散控制阶段、污损生物成长控制阶段和微生物腐蚀控制阶段等4个阶段。

Change of corrosion rate of carbon steels in seawater was discussed. Corrosion and biofouling character of carbon steels in seawater were summarized. The result showed that corrosion rate of the carbon steel exposed to seawater decreases with time, which is stable after one or two years of exposure;the corrosion course can be divided into the process dynamics controlled stage, the oxygen diffusion controlled stage, the growth of fouling organism controlled stage, and microbiological corrosion controlled stage.
