1. A component comprising:

a steel substrate having a structure that can be transformed into a martensitic structure,

a metallic intermediate layer which covers the steel substrate,

and

an anticorrosion coating covering the metallic intermediate layer,

wherein the anticorrosion coating comprises one or more layers and at least a layer of the anticorrosion coating adjoining the metallic intermediate layer is metallic and differs in terms of material from the metallic intermediate layer, and

wherein the metallic intermediate layer comprises greater than or equal to 90% by weight titanium, based on the total mass of the metallic intermediate layer.
