The first stage of UDC is initiation of a pit or crevice.
The second stage of UDC is either general corrosion propagation or passivation.
The transition between these stages could be assessed by EIS analysis.
Mechanistic information of each stage could be specified by EPN transients.
SEM analysis confirmed the correctness of the combined EIS and EN research approach.
