ABSTRACT:
The invention relates to a plated steel sheet for cans which must have high workability and corrosion resistance and can prevent bimetallic corrosion and a method of manufacturing the same. The plated steel sheet is manufactured by forming an electroplated chromium layer on the surface of a steel, removing a hydrated chromium oxide layer formed on the surface of the chromium layer, and forming an aluminum plating layer, so that the electroplated chromium layer and the aluminum plating layer are stacked in direct contact with each other. Another plated steel sheet is manufactured by forming a vacuum deposited chromium layer on the surface of a steel, and forming an aluminum plating layer.
