Abstract

X-ray photo-electron spectroscopy was used to study the surface composition of stainless steel (AISI 304) after active corrosion in 2.5 M H₂SO₄ or 2.5 M H₂SO₄ + 0.5 M NaCl solutions under electrochemically controlled conditions. Using two models with different assumptions about the element distributions, possible concentration profiles for Fe, Cr, Ni, Mo and Cu in their metallic and oxidized states were evaluated. It was concluded that Ni, Cu and Mo are enriched in their metallic states on the surface, possibly mainly on separate surface regions not containing Fe and Cr.
