METHOD OF ELECTROCHEMICAL NOISE MEASUREMENTS FOR CHARACTERIZATION OF LOCAL CORROSION PROCESSES

Janusz Smulko

Abstract

The new method of electrochemical noise (current and voltage fluctuations) measurements is presented. The proposed method can characterise local corrosion events while the other electrochemical methods are much less effective than electrochemical noise measurements. The new measurement setup is proposed. The system can identify metal surface where local corrosion events take place. The realized measurement system is described in detail. All the practical problems of noise measurements and methods of outside distortion reduction are presented. The preliminary measurement results are also discussed.
