Resumo
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.
