The influence of hot-stamping process on the corrosion properties of Al-Si coating on 22MnB5 steel was locally evaluated using a depth profiling approach combining GDOES and electrochemical micro cell. 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.Coordena????o de Aperfei??oamento de Pessoal de N??vel Superior (CAPES)Conselho Nacional de Desenvolvimento Cient??fico e Tecnol??gico (CNPq)CAPES: 88881.189691/2018-01CNPq: 205368/2018-2
