“…With the addition of 1000 ppm HAc, the WL corrosion rates for all specimens generally increased to about 2 mm/yr except for annealed steel specimen at 1.5 mm/y as shown in Figure 6. The results were in agreement with the LPR results [18]. Overall, the corrosion rates for all specimens were higher because of the addition of acetic acid at pH 5.5 that provides additional hydrogen source for the cathodic reactions.…”

“…Several experimental studies and mathematical models have been reported about the effect of the hydrodynamic conditions on steel's CO 2 corrosion [102][103][104][105][106]. The flow conditions influence the severity of CO 2 corrosion since it impacts the mass transfer process and wall shear stress.…”

The recent failures in flexible pipes have motivated the exhaustive research of corrosion mechanisms on high-strength carbon steel armor wires that are the main structural compounds of those structures that mostly operate in seawater environments in the presence of carbon dioxide (CO2) and confined spaces. Recently, the literature reported discoveries about electrolyte properties (as Fe+2(aq)/HCO3-(aq.) ratio) and supersaturation, near neutral pH inside the confined space, multiphase reactions of contaminants present in CO2 gas, the formation and dissolution mechanism of FeCO3 film, and interaction of CO2 gas impurities with the corrosion scale. Therefore, this review is aimed at presenting an up-to-date narrative of the CO2 corrosion phenomenon in carbon steel, connecting background fundamentals with current data studies.

“…Despite relatively limited corrosion resistance, steel is used in large tonnages in marine applications, chemical processing, petroleum production and refining, construction and metal processing equipment 1,2 . The economic consequences of iron corrosion and its alloys in various industrial sectors, including oil and gas operations, are investigated 3 and therefore much efforts have been carried out to enhance corrosion resistance of steel 4,5 .…”

In this study, cerium-based conversion coating was deposited on steel X52 by dip immersion method. Cerium oxide/hydroxide is an environmentally friendly conversion coating. The effects of immersion times and immersion temperatures on corrosion properties of cerium conversion coating on steel X52 were studied. Its corrosion resistance in 3.5 wt.% NaCl solution was investigated by means of electrochemical impedance spectroscopy, potentiodynamic polarization, and surface techniques. The coated samples showed a significant decrease in corrosion rate and corrosion current decreased with increasing immersion time up to 60 s. In addition, electrochemical impedance data showed that in the presence of cerium oxide conversion coatings, the charge transfer resistance of aluminum increased. The experimental results indicated that the corrosion resistance decreased with increasing the operating temperature. Surface morphology and its chemical composition were analyzed by means of scanning electron microscopy and energy dispersive spectroscopy.
