- In-Situ Observation and Acoustic Emission Analysis for Corrosion Pitting of MgCl2 Droplet in SUS304 Stainless Steel
抄録
Acoustic emission with near-field detection and optical video microscope monitoring was proposed to investigate the pitting corrosion caused by the small magnesium chloride droplet. For the corrosion testing of work-hardened SUS304 stainless steel, four types of the detected waveforms were characterized by the wavelet analysis. After the high activity AE signals, the corrosion product sheet was extended without or with low activity AE signals. With the cross-section observations, the detected AE signals were mainly attributed to the following three sources, the longitudinal and transverse cracking around the covered pitting, cracking of the oxidation products, and the early stage of the corrosion potential fluctuation.<br>
