Title:
ホットスタンプ成形体
Document Type and Number:
Japanese Patent JP7440771
Kind Code:
B2
Abstract:
To provide a hot stamp molding excellent in end surface corrosion resistance and hydrogen penetration resistance even after electrodeposition coating.SOLUTION: A hot stamp molding 1000 includes: a steel base material 20; an interface layer 200 formed on the surface of the steel base material 20, contacting the steel base material 20 and consisting of an Fe-Al intermetallic compound; a main layer 100 formed on the interface layer 200; and a plating layer 10 having a coating weight of 15-160 g/m2. The plating layer 10 has a predetermined chemical composition; the main layer 100 has both a Mg-Zn intermetallic compound phase 120 including a MgZn2 phase and an Fe-Al containing phase 140; and when observing the diffraction image of an electron beam incident on the [100] direction on the MgZn2 phase by a transmission electron microscope, the proportion of the MgZn2 phase having satellite spots around a main spot is 5.0% or more by area ratio.SELECTED DRAWING: Figure 2
