- •
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.
