An aluminum-based coating of a flat steel product is applied in a hot-dipping method and comprises a mass percentage of silicon within a given range. The coating for a flat steel product, in particular for press mold hardening components, offers a shortened required minimum oven dwell time and a sufficiently large processing window when heating in an oven. This is achieved in that the surface of the coating has a degree of absorption for thermal radiation ranging between 0.35 and 0.95 prior to an annealing treatment, where the degree of absorption relates to an oven temperature ranging from 880 to 950° C. during the austenitizing annealing treatment. The invention additionally relates to an improved method for producing a flat steel product with an aluminum-based coating, to an inexpensive method for producing press-hardened components from such flat steel products, and to a press-hardened component made of such flat steel products.

The present disclosure provides a composite coating and a method for fabricating the composite coating. The composite coating comprises a polymer layer, a metal interlayer and an amorphous metal coating. The polymer layer is formed on a substrate and acts as a diffusion barrier layer, which is thick and dense enough to prevent the corrosive substances from penetrating into the substrate. The metal interlayer is formed between the polymer layer and the amorphous metal coating for improving the adhesion of the amorphous metal coating to the substrate.
