摘要
利用金相、电子探针、Ｘ射线衍射、萃取碳复型、金属薄膜等方法，对汽车用热镀锌板的镀层结构进行了形貌观察和相分析．结果表明，镀层可分为三层：紧贴着基体是Ｆｅ－Ａｌ层，它是由Ｆｅ－Ａｌ金属间化合物组成；中间层是Ｆｅ－Ｚｎ层，它是由Ｆｅ－Ｚｎ金属间化合物及Ｆｅ－Ａｌ－Ｚｎ三元系金属间化合物组成．最外层是Ｚｎ层，但混有Ｆｅ－Ｚｎ金属间化合物．
The phase structure and morphology of the coating of hot-dip galvanized steel sheet for cars were investigated by means of electron probe,X-ray diffraction,extraction carbon replica,metal film and optical microscope. It was found that the coating consists of three different layers: the Fe-Al intermetal compound close to α-Fe matrix,the middle layer composed of Fe-Zn and Fe-Al-Zn intermetal compounds and the Zn surface layer.
