Abstract
The present invention suppresses deterioration in the corrosion resistance of a worked portion resulting from working cracks in a Zn-based plated layer (3) in a workpiece (2) formed into a predetermined shape by performing plastic working on a Zn-based plated steel sheet (1) coated with a Zn-containing metal as a raw material. That is, plastic working is performed on a raw material that is a Zn-based plated steel sheet (1) to obtain a workpiece (2) having a predetermined shape, and thereafter, pressurization processing is performed on a worked portion in a sheet thickness direction to deform the plated metal, thus decreasing the width of working cracks in the plated metal. Accordingly, it is possible to reduce the deterioration in the corrosion resistance of the worked portion of the Zn-based plated workpiece.
