摘要：

The uptake of chloride (Cl-) by the passive oxide film on 316L austenitic stainless steel polarized at potentials below (less positive than) the pitting potential in 0.6 M NaCl solutions was studied using X-ray photoelectron spectroscopy (XPS) and compared to our previous work on aluminum. The XPS spectra for the stainless steel showed that chloride was not adsorbed or present in the passive oxide film. This is quite different from the case of aluminum, where XPS data for the presence of chloride on the surface and incorporated into the oxide film are unambiguous. These differences in the adsorption and incorporation of chloride for these two metals will be discussed in the context of the mechanisms of passive film breakdown.
