<p>A hot-dip zinc coated steel sheet, characterized in that it comprises a steel sheet having the chemical composition, in mass %: C: 0.05 to 0.40 %, Si: 0.2 to 3.0 %, Mn: 0.1 to 2. 5 %, and the balance: Fe and inevitable impurities, and, formed on the surface thereof, a Zn plating layer comprising 0.01 to 1 % of Al and the balanced amount of Zn and inevitable impurities, and further has, inside the base steel sheet and in the area within 2μm from the interface between said plating layer and the base steel sheet, particles of one or more oxides selected from an Al oxide, an Si oxide, Mn oxide, and a composite oxide comprising two or more of Al, Si and Mn; and a method for producing the hot-dip zinc coated steel sheet. The hot-dip zinc coated steel sheet is excellent in the adhesion of the plating layer and combines a high strength and good formability, and further can be produced by means of a conventional apparatus for continuous zinc hot-dip galvanizing with no modifications or additional steps at a low cost.</p> |
