Abstract

 An investigation into the electrochemical noise generation during Stress Corrosion Cracking (SCC) of austenitic stainless steel 304 in acidified 25%MgCl2 and 70-30 brass in Mattson's solution was conducted. Initiation and propagation of cracks in both specimens can be recognized from the fluctuations of potential and current. Nucleation of cracks in stainless steel 304 is accomplished with spontaneous jumps in both current and potential with slow recovery, while, at the final stage of failure, the intensity of fluctuations are so high.In brass, sample initiation and propagation of cracks, is accomplished by spontaneous jumps of current and potential with non-complete recovery. The relation between potential and current fluctuations has been evaluated in the time domain and the obtained data has been analyzed in the frequency domain using Power Spectral Density (PSD). According to the obtained results, it was found that there are good relations between the current and potential noise caused by initiation and propagation of cracks during SCC, which may be used for SCC monitoring.
