Fig.6. Electrochemical equivalent circuit of EIS (Re—solution resistance, CPE1—electrochemical response of the passivation film, R1—hindrance of passivation film to ion migration, CPE2—electrochemical potential of the electric double layer, R2—corresponding charge transfer resistance, Q and n are the admittance value and fitted exponential of CPE, respectively)
