Description

Plated steel sheet with two plating layers and excellent in lubricity, corrosion resistance and paintability

Since this is an open matter, no full text was included.

1 shows the relationship between the friction coefficient of a plated steel sheet and the plating amount of an electroplated layer as an upper layer for a plated steel sheet of the present invention having a galvanized layer as a lower layer formed on the surface of the steel sheet and an electroplated layer as an upper layer formed thereon. graph,

2 is a schematic front view showing a device for measuring a coefficient of friction.
