钢结构在海水中会发生较严重的腐蚀,而牺牲阳极保护则是防止水下腐蚀的有效措施之一。该保护方法的关键是如何冶炼并筛选出性能良好的阳极材料。自1977年以来,我们配合冶炼部门不断总结并改进了筛选方法,还进行了显微组织分析及扫描电镜分析,初步找出了材质优劣的内因,为冶炼部门改善冶炼工艺提供依据。目前已筛选出 The steel structure will cause more serious corrosion in seawater, and sacrificial anode protection is one of the effective measures to prevent underwater corrosion. The key to this method of protection is how to smelt and screen good anode materials. Since 1977, we cooperated with the smelting department to continuously summarize and improve the screening methods. We also conducted microstructure analysis and scanning electron microscopy analysis to find out the internal factors of the quality of the materials and provide basis for the smelting department to improve the smelting process.
