Influence and role of ethanol minor constituents of fuel grade ethanol on corrosion behavior of carbon steel

Inhibition of carbon steel corrosion in phase-change-materials solution by methionine and proline

“…It is clear from Fig [47][48][49][50] . The Met and Pro molecules can adsorb on steel surface and form inhibition films to effectively protect it away from the aggressive Cl -ions, and then decrease the dissolution rate of iron in PCMs solution.…”

“…12): firstly, the between Cl -ion and metal atom [48,49] . Thus, the corrosion of steel in PCMs can be accelerated by Cl -ions since corrosion product of Fe2O3 or NH4FePO4·nH2O is subsequently converted into soluble FeCl3 and dissolved in PCMs solution.…”

“…It indicates that the anodic dissolution of steel and cathodic oxygen corrosion reaction are both suppressed by the inhibitors in PCMs solution, but the inhibitory degree of anodic dissolution reaction is higher than the inhibitory degree of cathodic oxygen corrosion reaction. The anodic dissolution reaction of steel in PCMs solution can be accelerated by Cl -ions present in PCMs solution with the pH of 6.5 (near neutral solution) [47][48][49][50] . The Met and Pro molecules can adsorb on steel surface and form inhibition films to effectively protect it away from the aggressive Cl -ions, and then 12 decrease the dissolution rate of iron in PCMs solution.…”

Corrosion of martensitic stainless steel in ethanol-containing gasoline: Influence of contamination by chloride, H 2 O and acetic acid

“…A majority of these studies deals with corrosion of carbon steel or low-alloyed steels in fuel grade ethanol or in ethanol-gasoline blends [9][10][11][12][13][14][15][16]. Stress-corrosion cracking of carbon steel in ethanolic environments has been widely studied (see e.g.…”

Corrosion of sedimentary liquids on internal bottom plate of tanks among coal liquefaction process

“…The Ca 2+ with higher content in this regard benefits to form precipitated scaling and inhibits the dissipation of dissolved free oxygen, which can result in the formation of oxygen‐concentration cell corrosion; conversely, it also improves the electro‐conductibility of sedimentary liquids and enhances the electron transfer, which leads to the acceleration of corrosion reaction . The Cl − is a corrosive catalyst accompanying with high polarizability, which can reinforce the corrosivity of sedimentary liquids . However, the is provided with corrosion inhibition and able to weaken the corrosivity with the existence of Cl− in the sedimentary liquids, which can advance the resistance of passive film to corrosion .…”
