ELECTROCHEMICAL NOISE AS A LOCALIZED CORROSION INDICATOR

Systems and methods are presented for a method for measuring or monitoring localized corrosion in which an electrochemical noise (ECN) signal is sensed and filtered by a high-pass or band-pass filter to remove low frequency components not related to localized corrosion and a standard deviation of th...

Beschreibung
Zusammenfassung:	Systems and methods are presented for a method for measuring or monitoring localized corrosion in which an electrochemical noise (ECN) signal is sensed and filtered by a high-pass or band-pass filter to remove low frequency components not related to localized corrosion and a standard deviation of the filtered signal is computed and scaled to provide a localized corrosion value.
