摘　　要：在Fe-B合金的基础上加入Si、C等元素并研究了C、Si对该合金耐锌的影响．结果表明，在Fe-B合金中加入0．5mass％～8．0mass％Si以后，Si固溶在α-Fe中，随着Si含量的增加，该合金的耐蚀性增强，但晶粒变大。力学性能下降；Si含量为1．5mass％时，该合金的腐蚀速度出现最低值；在Fe-B合金中加入C起分散化合物的作用，增加材料中网格的数量，细化晶粒，提高其耐蚀性和力学性能；同时生成的碳化物提高该合金的耐蚀性能．A Fe-B alloy has good heat conductivity and excellent corrosion resistance to molten zinc, thereby its application may be benefit for lowering the manufacturing cost for galvanizing production. In this paper, on the basis of previous Fe-B alloy, we add some elements such as carbon and silicon to enhance the corrosion resistance of α-Fe and refine the microstructure of B-eutectics while keeping the same proportion of intermetallic compound in the alloy, as well as to enhance the mechanical properties of the material, so that it can be used in real production.
