摘要One to one correspondence of single current transient and its 2D and 3D metastable pit geometry for 304 stainless steel microelectrode (50 mu m in diameter) in 6% FeCl3 solution have been investigated under potentiostatic polarization. Atomic Force Microscope (AFM) has been proved useful to measure the irregular-shaped pit volume without inclusions in it. The pit volume measured by AFM is consistent with that calculated from the charge passed from the corresponding current transient during pit growth. This result demonstrates that the effects of H-2 evolution inside the pit under relatively high potential can be neglected. The growth kinetics of the detected metastable pit obeys a power law, but the exponent n varies with time during the growth stage, which may be associated with the change of the hole diameter in the cover. This result indicates that the metastable pitting growth process is quite complicated and the assumed constant exponent n is unreasonable.
