摘要	The corrosion behavior of 316L stainless steel (316L SS) has been investigated in solutions containing various concentrations of chloride ions by using potentiodynamic polarization, capacitance measurement and Mott-Schottky relationship analysis (M-S). The result indicates that passive currents change slightly with the addition of chloride ions. The pitting potential (E-pit) decreases linearly with log[Cl-]. Correspondingly, the point defect diffusion coefficient (D-o) of the passive film increases linearly with increasing log[Cl-]. The results also indicate that the pitting corrosion of 316L SS follows the adsorption mechanism in NaCl solution.
