Reliability and Usefulness of Causality Factors of Electrochemical Frequency Modulation

摘要

In this paper the importance of causality factor 2 and causality factor 3 of electrochemical frequencymodulation (EFM) for corrosion monitoring has been discussed in comparison to two newly foundcausality factors. The derivation of these new causality factors namely causality factor 4 and causalityfactor 6 has been summarized. Moreover, the reliability and usefulness of EFM along with its causalityfactors to monitor pitting, stress corrosion cracking (SCC) and uniform corrosion for differentcorroding systems has been discussed. In many cases, EFM claims to be a suitable corrosionmonitoring technique because of good comparisons with other corrosion measurement methods.
