XPS Investigation on the Corrosion Behavior of 13Cr-Martensitic Stainless Steel in CO₂-H₂S-Cl⁻Environments

An Electrochemical-AFM Study of the Initiation of the Pitting Corrosion of a Martensitic Stainless Steel

“…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.…”

Corrosion behavior of SM 80SS tube steel in stimulant solution containing H2S and CO2

“…Moreover, uniform corrosion and some scattered acerate pits occurred on the surface of SM 80SS tube steel. Masamura et al [23] and Fierro et al [24] presented that when P CO 2 /P H 2 S > 200, CO 2 played a leading role in this system, but, there would form a layer of compact FeS scale on the tube steel surface reducing the corrosion rate. While, when P CO 2 /P H 2 S < 200, the FeS scale would firstly formed, which hobbled the protective FeCO 3 scale coming into being.…”

Tribological and Antioxidation Synergistic Effect Study of Sulfonate-Modified Nano Calcium Carbonate

“…The binding energy peak of C 1s appears at 289.8 eV, which is identified as C in carbonate [15]. Besides, the binding energies of C 1s at 284.9 eV directly correspond to C-H and C-O, which existing in the additive and base oil, and it means that the base oil and additive were adsorbed on the metal surface.…”
