| Abstract | The acoustic emission (AE) technique was applied to monitor the pitting corrosion of 13 carbon steel in NaHCO3 + NaCl solutions. The open circuit potential (OCP) measurement and the 14 corrosion morphology in-situ capturing using optical microscope were conducted during AE 15 monitoring. The corrosion micromorphology was characterized with scanning electron microscope 16 (SEM). The propagation behavior and AE features of natural pitting on carbon steel were 17 investigated. After the performing of signal processing including pre-treatment, shape preserving 18 interpolation and denoising for raw AE waveforms, three types of AE signals can be classified in 19 the correlation diagrams of new waveform parameters. Finally, a 2D pattern recognition method 20 was established to calculate the similarity of different continuous AE graphics, which is quite 21 effective to distinguish the localized corrosion from uniform corrosion. 22 |
