| 中文摘要: |
| 目的 研究南海岛礁环境浪花飞溅区中典型不锈钢的腐蚀规律。方法 在南海岛礁进行现场腐蚀试验，利用表面微观形貌观测、腐蚀产物分析及失重测试等手段，对比分析了304、316L和2205不锈钢在浪花飞溅区中的腐蚀形貌、腐蚀速率和腐蚀深度。结果 在浪花飞溅区，304不锈钢的腐蚀速率最大，316L不锈钢次之，2205不锈钢最小；在浪花飞溅区304不锈钢和316L不锈钢局部腐蚀主要以点蚀和缝隙腐蚀为主，2205不锈钢耐腐蚀性良好，局部腐蚀不明显；三种不锈钢的腐蚀产物主要包括α-FeOOH、γ-FeOOH、γ-Fe2O3。结论 三种不锈钢的腐蚀产物基本相同，但2205不锈钢腐蚀速率变化趋势与另外两种不锈钢明显不同。 |

| In order to study the corrosion regularity of typical stainless steel in splash zone in island environment of the South China Sea, field corrosion tests were carried out on islands in the South China Sea. The corrosion morphology, corrosion rate and corrosion depth of 304, 316L and 2205 stainless steels in splash zone were compared and analyzed by methods of surface morphology observation, corrosion product analysis and weight loss test. The results show that the corrosion rate of 304 stainless steel in splash zone is the highest, followed by 316L stainless steel, and 2205 stainless steel is the lowest. Pitting corrosion and crevice corrosion are the main corrosion types of 304 stainless steel and 316L stainless steel in splash zone. 2205 stainless steel has good corrosion resistance, but local corrosion is not obvious. The main corrosion products of these three stainless steels are α-FeOOH, γ-FeOOH and γ-Fe2O3. The corrosion products of the three stainless steels are basically the same, but the change trend of corrosion rate of 2205 stainless steel is different from that of the other two stainless steels. |
