20110256420 | HOT-DIP GALVANIZED STEEL PLATE AND PRODUCTION METHOD THEREOF - 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 Γ phase, but has relatively thin δ phase and little ξ phase. The plating layer mostly consists of η phase, thus obviously improving adhesion, scratch resistance and wear resistance of the plating layer. | 10-20-2011 |
