AbstractThree incremental passivation potentials (0.2, 0.5, and 0.8 V-SCE) were selected to passivate the 316L-Cu stainless steel (SS) and the 316L SS in 0.5 M H2SO4 solution, with the aim to investigate the corrosion resistance differences of two SSs in 0.9 wt.% NaCl solution. Various electrochemical tests including potentiodynamic polarization, electrochemical impedance spectroscopy (EIS), and Mott-Schottky analytical method assisted with X-ray photoelectron spectroscopy (XPS) were employed. The results indicated that 316L-Cu SS after passivation in 0.5 M H2SO4 solution showed no influence on the double-layer structure of passive films. Besides, increased passivation potential augmented the electron donor concentration (N-D) and the hole accepter concentration (N-A) of the passive film on the 316L-Cu SS, hinting a gradually declined compactness of the passive film. EIS results further affirmed that the passive film stability of 316L-Cu SS followed the same tendency with increased passivation potential. XPS results hinted that the oxidation reaction of Cu element switching into Cu2+ and Cu+ ions promoted the dissolution of Cu ions and weakened the passive film stability of 316L-Cu SS.
