Electrochemical Noise Measurement Technique in Corrosion Research

摘要

Electrochemical noise measurement is one of the novel techniques currently being used in corrosionmonitoring. Two major methods of analysis in use are the Fast Fourier Transform (FFT) and theMaximum Entropy Method (MEM). This paper reviews the techniques fundamental background types of noise, physical data; description, classification and characteristics; mathematical backgroundof random data and spectral analysis. Recent progress made in its application to corrosion monitoringand other electrochemical reaction phenomena are also examined.
