With a corrosion-inhibiting steel sheet and method for coating a steel sheet with such a a corrosion protection system

摘要

The present invention relates to a flat steel products provided with a coating system, which in the coated state, an optimized combination of corrosion resistance and weldability has. According to the invention has, for this purpose, the steel product comprising a steel base layer and a on the base layer is applied a corrosion protection system, which is of less than 3,5 μm thick metallic coating, which consists of a first to the base layer applied metallic layer and a second to the first metal layer applied second metallic layer is formed, wherein the second metal layer with the first metal layer is a metallic alloy has formed, and a plasma polymer layer applied to the metallic coating comprises.
