Anodic dissolution and cathodic hydrogen evolution behavior of pure Fe in 5 mM HClO4solution was investigated via a modified tip generation/substrate collection mode using scanning electrochemical microscopy. The modified TG/SC mode of SECM could instantaneously divide the apparent current of Fe corrosion process into Fe oxidation and proton reduction process, and standard rate constants and transfer coefficients of hydrogen evolution and Fe oxidation are 9.2 × 10−6cm/s and 0.27, 2.5 × 10−6cm/s and 0.7, respectively, based on COMSOL simulation and Tafel linear fitting. Comparing with traditional polarization curve and electrochemical noise, the more accuracy corrosion current can be obtained in time.
