The results highlight the complexity of the system and the high dependence of the local galvanic series on the hot-stamping process. Due to iron diffusion from the steel substrate into the coating, the Al-rich layers presented active behaviour, whereas the initial coating condition showed a passive behaviour. Conversely, Fe/Si-rich sublayers acted as protective barrier for the steel substrate, as they show passive behaviour with nobler corrosion potentials and lower current densities.1-12openAccesscorrosioncoatingsaluminium compoundsaluminium silicidessteelshardeningArtigo de periódico18510.1016/j.corsci.2021.1094350000-0002-8304-99390000-0002-4987-3334https://orcid.org/0000-0002-8304-9939https://orcid.org/0000-0002-4987-333486.8489.67
