| 摘要: |
| 于1993年9月通过对241A，24KU，SS41三个不同钢种极化曲线的测定，对镜层本身的氧化还原电流的测定及X线分析，研究在海水一海气交换界面区锈层在腐蚀中所起的作用。结果表明，海一气交换界面区的钢由于锈层本身的氧化还原反应，其阴极电流均较裸钢为大，这说明锈层的还原反应起着重要作用．根据锈层本身的还原时间和还原电位，可以在某种程度上评价钢材本身耐腐蚀性能的好坏。 |

| Abstract: |
| The role of the rust layer in the corrosion process of steel at the juncture area between seawater and the atmospheric zone was studied through polarization curve measurement, rust layer, oxygenation-reduction current, and X ray analysis for 24IA, 24KU and SS41 steels. The results show that the cathodic current of steel with rust layer was larger than that of steel without rust layer because of the important oxygenation-reduction action of the rust layer. The corrosion-resistance of steel can be evaluated by reducing time and reduction potential of the rust layer to some extent. |
