  • HOT-DIP GALVANIZED STEEL PLATE AND PRODUCTION METHOD THEREOF
    Publication number: 20110256420
    Abstract: The invention provides a hot-dip galvanized steel plate with high adhesion between a plating layer and base steel, and belongs to the field of manufacturing hot-dip galvanized steel plates. Atomic concentration ratio Al/Zn of Al and Zn in a Fe-Al intermediate transition layer between a base steel and a plating layer of the hot-dip galvanized steel plate is 0.9-1.2. The plating layer did not have ? phase, but has relatively thin ? phase and little ? phase. The plating layer mostly consists of ? phase, thus obviously improving adhesion, scratch resistance and wear resistance of the plating layer.
