飞溅区挂样位置、高度对钢腐蚀的影响

目的研究飞溅区挂样位置、高度对钢腐蚀的影响。方法采用海水飞溅区暴露试验。结果在青岛和三亚获得了5种钢在飞溅区暴露的腐蚀结果。结论在不同海域试验地点的飞溅区暴露,因环境条件不同,钢的飞溅区范围区间有较大差别,腐蚀速率峰值相对平均高潮位的高度也不同。在同一试验地点,暴露位置、条件的不同都会使钢的飞溅区范围区间及腐蚀速率峰值的高度不同。

Influences of Position and Height of Exposure on Corrosion of Steels in Splash Zone

Objective To research influences of exposure position and height on corrosion of steels in splash zone. Methods Exposure test was carried out in the splash zone of seawater. Results Corrosion results of five kinds of steel in Qingdao and Sanya were obtained. Conclusion Large difference exists in the corrosion range and peak value of corrosion rate when steels are exposed in different test sites of sea areas because of different environmental conditions. Meanwhile, in the same test site, different exposure position and conditions can cause different range of splash zone and peak value of corrosion rate.
