Abstract

PURPOSE: To develop the resistance weldability excellent in terms of both of a welding current value and electrode contact resistance by subjecting the surface of a steel sheet to plating to two layers consisting of a ceramics-contg. plating layer dispersed with Zn as a lower layer and a Zn layer as an upper layer.
CONSTITUTION: The plating layer dispersed with Zn or Zn alloy contg. ≥1 kinds among the oxides, nitrides and carbides of Al, Si, Cu, Ti, Cr, Mn, Fe, Co, Ni, Zr, Nb, Pb, Ca, and Mg at (0.03+1.5/1,000×y)wt.% in total is formed at 3W200g/m2 as the lower layer on the surface of the steel sheet. (Here, y is the weight of the plating expressed by g/m2). The Zn or Zn alloy plating layer having <0.03% total concn. of the oxides, nitrides and carbides is formed to 0.3W8g/m2 as the upper layer thereon. The performances of the lower layer and the upper layer are thereby balanced and the excellent resistance weldability is developed in the two-layer plated steel sheet. Furthermore, the corrosion resistance of the painting in the worked part is improved by incorporating ≥1% Cr into the lower layer.
