摘要	Current transient measurements and electrochemical noise (EN) method have been used to characterize the metastable pitting events for Al-Mg-Si microelectrodes (diameter 50 mu m) in deaerated neutral 0.5 M NaCl solution. The results are compared with those obtained by atom force microscopy and scanning electron microscopy. The pit numbers determined by shot noise analysis at open circuit potential and by current transient analysis at -1.2 V (SCE) are both significantly less than those determined by corrosion morphology image analysis. These results indicate that larger discrepancies can be introduced if the anodic and cathodic reactions localize severely on the same electrode. (C) 2013 Elsevier Ltd. All rights reserved.
