What this dataset tests
Whether a system can detect loss of coherence between
electrochemical impedance surface micro-pH pit nucleation signals
before visible corrosion failure.
Corrosion begins as relationship collapse not visible damage.
Required outputs
passivation_coherence_score
pit_growth_acceleration
breakdown_risk_flag
time_to_pitting
critical_surface_zone
protective_action
Use case
Marine alloys chemical plants energy infrastructure aerospace
Detect passivation collapse before pitting cascade.
