昆钢镀锌彩涂板镀锌层、彩涂层显微观察和分析

MICRO-OBSERVATION AND ANALYSIS OF KISCO GALVANIZING AND COATING PLATE

通过对昆钢镀锌板的显微组织进行扫描电子显微镜观察和能谱分析,观察到了很薄的铁锌合金层,找到了镀锌层和钢板界面形成Fe-al或Fe-Al-Zn合金层的证据。同时对镀锌、彩涂层中一些典型缺陷进行了观察,并探讨了缺陷产生的原因。

This paper observed and analyzed KISCO galvanizing plate by SEM and EDS.Microstructure was scanned. The thin Fe-Zn alloy layer was observed,the evidence of forming Fe-Al or Fe-Al-Zn alloy layer between galvanizing coating and surface of steel plate was found.Meanwhile some typical defects of the galvanizing coating,color coating were observed and discussed.
