spectroscopy (EIS) (a) and polarization curves (b) of P110 steel in annulus-simulated solution with different inhibitor levels (ptotal=9 MPa, 4 Discussion The electrochemical corrosion mechanism of CO2-H2S in aqueous solution is generally considered to be a reduction of hydrogen ions and production of iron sulfides and carbonates. The CO2 corrosion mechanism is as follows [13-16]: Anodic process......
for the blank (Fig.6(a)) and the PDH-covered Mg-Mn-Ce plates at E3 (Fig.6(b)). EIS measurement curves exhibit the same shape, which means they have the same corrosion mechanism, and the capacitive loop... of semicircles. It is supposed that the corrosion mechanism of the blank Mg-Mn-Ce alloy and the polymer-plated one Fig.6 Nyquist plots for Mg-Mn-Ce plates in 0.1 mol/L NaCl solution: (a) Blank; (b) Polymer......
