A component including a steel substrate having a structure that can be transformed into a martensitic structure, a metallic intermediate layer which covers the steel substrate and has a main constituent of titanium and an anticorrosion coating covering the intermediate layer, wherein the anticorrosion coating includes one or more layers and at least the layer of the anticorrosion coating adjoining the metallic intermediate layer is metallic and differs in terms of material from the intermediate layer.

Component comprising a steel substrate, an intermediate layer and an anticorrosion coating, corresponding hardened component and corresponding methods and uses

The present disclosure relates to a flat steel product comprising a steel substrate with, present at least on one side of the steel substrate, anticorrosion coating composed of zinc and unavoidable impurities. This anticorrosion coating has continuous microchannels which connect the steel substrate to an ambient atmosphere. Additionally, the present disclosure relates to a process for producing a flat steel product of this kind.

Flat steel product having an improved zinc coating

The invention relates to a steel component comprising a steel substrate having an anticorrosion coating present at least on one side of the steel substrate. This anticorrosion coating comprises a manganese-containing alloy layer. The manganese-containing alloy layer here forms the closest alloy layer of the anticorrosion coating to the surface. Moreover the manganese-containing alloy layer comprises iron and a further metal.
