Problems solved by technology

[0005] However, when the suppression layer is continuously formed at the interface between the base material and the plating layer, the diffusion of Fe is suppressed, so there are many restrictions on the use of the effect on the friction characteristics described above.

Embodiment Construction

[0067] Hereinafter, the present invention will be more specifically described by examples. However, it should be noted that the following examples are for illustrative of the invention for more detail, and is not intended to limit the scope of the invention. This is because the scope of the present invention is determined by the content described in the claims and the content that is reasonably derived.

[0068] (Embodiment)

[0069] As a test piece for plating, a cold rolled steel sheet (0.0016% C-0.081% Mn-0.002% Si-0.0091% of Mn-0.002%) of a cold rolled steel sheet (0.0016% C-0.081% Mn-0.002% of C-0.0091%) of a cold rolled steel sheet (0.0016% C-0.081% Mn-0.0043%). S-0.036% acid solulent aluminum (Sol.al)) is used as a base steel plate, followed by plating in Table 1, thereby manufacturing each galvanized steel sheet. At this time, the plating after plating is performed by ejecting nitrogen to the front and back surface of the steel sheet, and the first cooling is terminated at...

Abstract

The objective of one aspect of the present invention is to provide: a galvanized steel sheet having excellent plating adhesion, having a plated layer with improved friction characteristics by means of a predetermined level of Fe elution, and having excellent corrosion resistance; and a manufacturing method therefor.

Description

Technical field [0001] The present invention relates to a galvanized steel sheet, and more detail, involving a galvanized steel plate having excellent plating adhesion and corrosion resistance and a method of manufacturing the same. Background technique [0002] It is known that the existing hot dip galvanized steel sheet is present in an Inhibition Layer formed between the base material steel plate and the coating (interface), which ensures the plating stick in the interface of the base material steel plate and the plating. Attachment, and inhibit the concentration gradient caused by FE from the base material into the coating. [0003] When the interface of the base material and the plating cannot be continuously generated, Fe is dissolved into the plating layer in the base material, and there is a problem that the plating adhesion is lowered and the coating is peeled off. Therefore, in order to ensure a certain level of plating adhesion, a suppression layer is required. [0004...
