摘　　要：针对热镀锌行业中的熔融锌液对材料产生的腐蚀问题,通过向Fe-2.5B合金材料中分别添加1wt%的C、Si、Mn等微量合金元素,研究两相的微观形貌、腐蚀性能和力学性能的变化。结果表明:加1%C的影响较为明显,耐锌液腐蚀性能提高9倍左右,抗弯强度下降一半。加1%Si和1%Mn后α相略有减少,共晶组织骨架粗大致密,耐熔锌腐蚀性能和抗弯性能都有不同程度的提高。According to the problem of the moltening zinc-corrosion to materials in the hot-dip galvanizing industry, the changes of microstructure, corrosion resistance to molten zinc and mechanical properties were studied by adding C, Si, Mn alloying element into Fe-2.5B alloy. The results show that the corrosion resistance of Fe-2.5B-1C in moltening Zn increases about 9 times, but bending strength decreases half when adding 1%C. The α phase and dense eutectic structure reduce when adding 1% Si and 1% Mn. The corros...
