Abstract

A striplike or sheetlike steel substrate is hot-dip-coated with a metallic coating based on zinc and has a modified surface. A method includes producing a semifinished product with modified surface. The method includes at least regionally modifying the surface of a coated, skin-pass-rolled, oiled and cleaned metallic steel substrate by an atmospheric-pressure plasma treatment of surface regions with oxygen, air, forming gas or a mixture of two or more of these gases as process gas.
