从热镀锌板镀层铁含量、镀层剥离前截面与镀层剥离后的表面SEM观察分析，研究了镀层铁含量对镀层剥离性的影响。结果表明，铁含量和镀层剥离量成“倒置S”型曲线，在镀层中铁含量在1．19g／m2到1．32g／m2时，镀层的剥离量达到最低，同时各镀层剥离时均呈现犁沟特征。
From analysis of the Fe content in hot-dip galvanized steel sheet and observation of cross sectional mistructure of the coating before flaking and surface patterns after flaking, the effect of Fe content in coating on flaking resistance of hot-dip galvanized coating was studied. The results show that the relationship between the Fe content in coating and coating flaking was as an "inverted S" curve, when the Fe content in the coating was 1.19 g/m2 to 1.32 g/m2 , the amount of coating flaking was minimal, and the coatings all showed a pear channel characteristics.
