摘　　要：针对当前热镀锌行业亟待解决的液态锌腐蚀问题,依据腐蚀理论和金属理论对材料进行微观设计。利用共晶原理构造一种新型三维网格合金Fe-Al-B-Mo-W,并研究了其在600℃的锌液中的腐蚀行为。利用扫描电子显微镜观察了腐蚀界面,并对腐蚀产物进行了能谱分析。结果表明,合金在锌液中的腐蚀是一个反应扩散和溶解的过程,但是网格结构抑制了锌原子向基体中的扩散,使合金具有良好的耐蚀性能。In view of liquid zinc corrosion problem to be settled urgently in the hot galvanizing industry, the micro-design of material is done based on corrosion theory and metal theory. A new three-dimensioned gridding alloy Fe-Al-B-Mo-W is formed by eutectic theory, and its corrosion in the 600 ℃ liquid zinc is studied. The corrosion interface is observed by scan EMS and the spectrum analysis of corrosion products has been done. The result shows the corrosion in liquid zinc is a process of reaction diffusion and dissolusion. However, the diffusion of zinc atom is restrained by gridding structure making the alloy resistant to corrosion.
