“…Figure 4b indicated that only trace of oxygen in oxide form remained on the surface after ion bombardment. All these attributions are in accordance with the literature [19][20][21][22]. Thanks to EDX and XPS analysis, we can conclude that the particles were in fact precipitates of chromium and that carbide is present on the surface.…”

“…Clayton and Lu [37] emphasized that Ni is rarely observed in the passive films of stainless steels. The presence of metallic Ni spectra in S31254 highalloy austenitic stainless steel was reported by Olsson and Hornstrom [38]. However, no Ni oxide peak was found in their XPS spectra after testing the samples in FeCl 3 solution at the OCP.…”

We investigate the transpassivity of superaustenitic stainless steel UNS N08367 in 2.5 M LiCl solution by using cyclic potentiodynamic polarization (CPP), electrochemical impedance spectroscopy (EIS), and X-ray photoelectron spectroscopy (XPS). The CPP curve exhibits negative hysteresis, which indicates a transpassive dissolution process instead of pitting corrosion. The transition from the passive region to the transpassive region is characterized by EIS and equivalent circuit analysis. During the transpassive dissolution of the N08367 alloy, two reactions of adsorbed intermediates are dominant, as indicated by the two inductive loops at the transpassive region. The first inductive loop is associated with the faster reaction, i.e., the adsorption of Fe intermediates. This fast reaction is significantly influenced by the preferential dissolution of Fe during the transpassive dissolution. The second inductive loop is correlated with the adsorption of the Cr intermediate. In contrast to Fe, the Cr content on the surface increases in the transpassive region compared with the content in the passive region. The XPS spectra support the time and frequency domain approach for the preferential dissolution, and the dominant species resulted from the interfacial processes at the transpassive region.

“…The second one, less intensive (531.4 eV), is possible to ascribe to the relations with carbon [15]. And the last and weakest component with binding energy at 533.01 eV matches the oxygen linked with hydrogen in water molecules [16].…”

(NH4)2−xHxV9Mo3O 31±δ ·nH2O (x = 0, 1) gels were produced from V2O5, NH4VO3, 40% H2O2, and Mo powder by using sol-gel technology. Synthesized gels were investigated by X-ray photoelectron spectroscopy methods. The shape and position of the complex core photoelectron lines V 2p, O 1s, C 1s, Mo 3p, Mo 3d, and N 1s were analysed for the gels with different x values. The valences of the V and Mo ions, which have an important role in the electrical conductivity of the compounds, was studied. It has been found that the molybdenum is in the stable Mo 6+ state. The vanadium ions are in V 5+and V 4+ states. The reduction ratio of vanadium ions is about 0.043 independent of the x value. The position of the N 1s peak indicates that the nitrogen is connected with hydrogen in NH4 ions.
