摘要: 应用SEM和EDS研究了锌液中不同Al含量对镀层组织结构和抑制层的影响，进而确定440MPa级高强IF钢镀层成形性的最佳Al含量。结果表明，随着锌液中Al含量的增加，纯锌层与基体界面处ζ相明显减少，Al的富集程度增加，抑制层的晶粒逐渐长大，致密性增加。当锌液中Al含量为0.25%时，镀层成形性最好。

关键词 ： Al含量, 镀层组织结构, 抑制层, 440MPa级高强IF钢

Abstract：The influence of Al content in zinc bath on coating structure and inhibition layer were studied by scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and line scanning. The results showed that with increasing Al content in zinc bath, the quantity of ζ phase decreased significantly and Al enriched, but grain size and density of inhibition layer increased. The optimal Al content for good coating formability on 440 MPa IF-HS steel was 0.25%.

Key words： Keywords: Al content coating structure inhibition layer 440 MPa IF-HS Steel
