| 目的 研究AH36钢在西沙海域不同区带的腐蚀行为。方法 通过在西沙海域不同区带进行暴露试验，回收后进行腐蚀质量损失、形貌及产物成分分析。结果 试样在不同区带的腐蚀质量损失与周期之间遵循幂函数变化规律，飞溅区试样腐蚀速率最快。大气区试样发生较轻的全面腐蚀，飞溅区试样表面可观察到大量明显蚀坑，全浸区试样发生不均匀全面腐蚀。不同区带腐蚀产物均以稳态的α-FeO(OH)以及铁氧化物为主，飞溅区试样腐蚀产物中，稳态物质含量高于大气区，全浸区试样腐蚀产物中含有钙镁沉积物。结论 AH36钢在西沙海域不同区带腐蚀速率快，飞溅区腐蚀最为严重，腐蚀产物生成及转化速度快，腐蚀易趋于稳定。 |

| Objective To study corrosion behaviors of AH36 steel in different seawater zones in Xisha. Methods The test was made by corrosion weight loss, morphology and product composition analysis after exposure in different seawater zones in Xisha. Results The power function was observed between the corrosion weight loss and exposure time in different zones, and the corrosion rate of the samples in splash zone was the highest. Slight general corrosion occurred at atmospheric zone sample, while obvious corrosion pits were observed on splash zone sample surface. Non-uniform comprehensive corrosion occurred in the submerged zone. The stable α - FeO (OH) and iron oxides were the main corrosion products in different zones, which were higher in splash zone than in atmospheric zone. Besides, calcium and magnesium deposits were also detected in corrosion products of samples in the submerged zone. Conclusion The corrosion rate of AH36 steel in Xisha sea area is fast, with the most serious corrosion of samples in the splash zone. The rate of corrosion products formation and conversion is fast, and the corrosion tends to be stable. |
