Abstract
In this paper, a set of experiments scanning real potential variations inside cavities under current control were employed to characterize local electrochemical information. The limiting diffusion current and the critical currents sustaining the supersaturation of dissolved gas and completed oxide film-formation were selected as the reference currents. It is demonstrated that for gas-evolving electrode, only the bubble sealing the cavity remarkably increases the total potential variation within cavities. Combined with the theoretical analysis and measurement results, kinetic parameters range inside cavities can be indirectly derived.
