Abstract:The properties of the passive film formed on 2205 stainless stee1 in acetic acid at high temperature that contained chloride
ions were studied by atomic absorption spectrometry(AAS),X—ray photoelectron spectroscopy(XPS),and electrochemical polarization
meas~ements.AAS results show that toolybdenum is enriched on the surface as the passive film is dissolved.This enrichment
decreases the corrosion resistance because it hinders chloride adsorption and Fe ion dissolution.and acts as a local pH buffer because
n consumes protons.The dissolution ratio ofFe/Cr is approximately 10 during the active dissolution ofthe passive film.XPS results
indk:ate that when the potential is in the passivation region,Cr comprises about 50% of the mc协1 cations in the near-surface region
of the passive fiIm and is the main metal constituent in this region.W hen the polarization potential is much greater than the transpas.
sivation potentia1.the Mo content accounts for approximately 45% of the meta1 cations in the near.surface region;Fe and Ni have no
obvious influence on the formation,dissolution,or puncture of the passive film.
Key words:acetic acid;corrosion;electrochemical behavior;stainless steel;passive film
