摘要： A hot dip zinc plated steel sheet which comprises a steel sheet containing 0.1 to 3.0 mass % of Si, a hot dip zinc plating layer, and, formed between said steel sheet and said hot dip zinc plating layer, a layer enriched in at least one component of selected from the group consisting of S, C, Cl, Na, K, B, P, F and N which contains an oxide containing Si and has a thickness of 0.01 to 100 µm. Said hot dip zinc plated steel sheet is free from the non-plating phenomenon, exhibits fine surface appearance and is excellent in the adhesion of a plating layer and sliding characteristics, although it uses a base steel sheet having a relatively great Si content. Further, an alloyed hot dip zinc plated steel sheet produced by alloying said hot dip zinc plated steel sheet is excellent also in the resistance to powdering.

摘要： A coated steel sheet includes a corrosion-resistant coating composed of at least one layer selected from the group consisting of a Ni layer, a Sn layer, an Fe-Ni alloy layer, an Fe-Sn alloy layer, and an Fe-Ni-Sn alloy layer disposed on at least one surface of a steel sheet, and an adhesive coating disposed on the corrosion-resistant coating, the adhesive coating containing Zr and further containing at least one metal element selected from the group consisting of Co, Fe, Ni, V, Cu, Mn, and Zn, in total, at a ratio by mass of 0.01 to 10 with respect to Zr. The coated steel sheet has excellent humid resin adhesion and corrosion resistance, in which streaky surface defects do not occur. Accordingly, when the coated steel sheet is coated with a resin, it is possible to obtain a resin-coated steel sheet excellent in the properties described above. Furthermore, in a method for producing the coated steel sheet, it is not necessary to use Cr which is strictly environmentally regulated.
