| 摘要 |
<p>The present invention relates to an electrogalvanized steel sheet having improved plating quality and a manufacturing method thereof. The present invention provides an electrogalvanized steel sheet which forms a graphene layer by coating graphene on a surface of a substrate steel sheet prior to performing an electrogalvanization to the substrate steel sheet to inhibit surface defects generated by minute scales remaining on the substrate steel sheet, thereby an electrogalvanized steel sheet having excellent surface quality and corrosion resistance improved by the graphene layer.</p> |
