摘　　要：通过SEM、GDOES和电化学研究了相同合金化温度、不同合金化时间条件下高强IF钢合金化镀锌板表面组织及镀层Fe含量对耐蚀性的影响。研究表明:随着保温时间的延长,镀层表面铁含量较高的Fe-Zn相形成,镀层中的铁含量增加,其耐蚀性更好。。The effects of surface microstructure and Fe content in coating on the corrosion resistance of high strength IF galvarmeal sheet were studied by SEM, GDOES and electrochemical experiment. The results show that with holding time increasing, Fe-Zn with higher content of Fe appears on the coating, then, the Fe content in the coating increases, the corrosion resistance of the coating becomes better.
