<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 2 mum 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> |
