XPS measurements of LDX 2101 duplex steel surface after magnetoelectropolishing

  • Krzysztof Rokosz and Tadeusz Hryniewicz


The work presents the X-ray photoelectron spectroscopy measurement results of LDX 2101 duplex steel surface after magnetoelectropolishing in comparison with the results obtained after a standard electropolishing in still electrolyte and in the electrolyte with moderate mixing. A considerable improvement of the steel surface was found to appear after the magnetoelectropolishing treatment concerning the general composition. The calculated ratio of chromium compounds to iron compounds Cr-X/FeX equals 2 after magnetoelectropolishing and only 0.5 after a standard electropolishing. On the other hand, the ionic Cr6+ content after magnetoelectropolishing was the lowest (2.77 at.%), and after a standard electropolishing it was the highest (30.3 at.%). Such results are expected to influence the corrosion behavior of the steel and increase the corrosion resistance greatly.
