The corrosion of Fe3Si alloy in molten zinc was controlled by at- tacking the grain boundaries preferentially. Aluminum reacted with iron of Fe3Si alloy firstly while the samples were immersed in molten zinc, although aluminum contents in the molten zinc were very low. The phase of reaction product was thought to be Fe2Al5. The corrosion rate of the Fe3Si alloy in molten zinc was determined to be approximately 2.9×10?3 mm/h, therefore the liquid zinc cor- rosion resistance of Fe3Si alloy was very weak. 关键词：铁硅合金液锌等温腐蚀热浸镀锌金属间化合物
