Abstract
Modal acoustic emission technique was used to analyze corrosion signals produced by polarization corrosion of LY12CZ aluminum alloy. The results showed that there were two-type waveforms for both anodic and cathodic polarization. Only extensional signals appeared within 1800 s, but extensional and flexural signals both appeared beyond 1800 s. The frequency spectrums were presented and analyzed, and potential source identification was discussed.
