| 摘要 |
The present invention provides a processed component (2) that is formed into a prescribed shape by plastic working, using, as a raw material, a galvanized steel sheet (1) coated with a Zn-containing plating metal, wherein a reduction in corrosion resistance of a processed portion caused by processing cracks in a galvanized layer (3) is suppressed. That is, the processed component (2) having a prescribed shape is obtained by subjecting the galvanized steel sheet (1) raw material to plastic working, and the processed portion is then subjected to pressurization in the sheet thickness direction, thereby deforming the plating metal and reducing the widths of processing cracks in the plating metal. Due to this configuration, it is possible to reduce deterioration of corrosion resistance in a processed portion of a galvanized component. |
