a Potentiostatic polarization curves of Ni foil tested in ClE and BrE at a potential of 1.33 V vs. RHE. b–d Corresponding morphology of pits on Ni foil corroded by Cl− and Br−, and both Cl− and Br− during the potentiostatic polarization tests. e α-cycle plots obtained by fitting the slope of linear part in the high frequency region in time-dependent imaginary part of the impedance-frequency plots. f, g Changing trends of SVET current density maps with time in ClE and BrE, respectively.
