Electrochemical study on carbon steel corrosion process in alkaline sour media

EIS characterization of tantalum and niobium oxide films based on a modification of the point defect model

“…The breakdown of oxide films may be promoted by the formation of molecular hydrogen at the metal-film interface, when a critical condition of pressure is reached. Experimental evidence for this phenomenon has been reported in the literature for different electrochemical interfaces [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17].…”

Quantum chemical calculations, synthesis and corrosion inhibition efficiency of ethoxylated-[2-(2-{2-[2-(2-benzenesulfonylamino-ethylamino)-ethylamino]-ethylamino}-ethylamino)-ethyl]-4-alkyl-benzenesulfonamide on API X65 steel surface under H2S environment

“…Surfactants are special type of organic compounds and exhibit unique properties due to their amphiphilic properties. The mechanism of corrosion process of carbon steel in aqueous medium containing H 2 S was discussed in former literatures [19][20][21][22][23][24].…”

Effects of environmental conditions on hydrogen permeation of X52 pipeline steel exposed to high H2S-containing solutions

“…The corrosion scale acted as a diffusion barrier for the species involved in the corrosion process can slow down the corrosion process and prevent the underlying steel from further dissolution [5]. Sosa [6], Cabrera-Sierra [7], Kittel [8], Hernández-Espejel [9] and Zhou [10] reported that the protective property of the sulphide film depended on the factors such as the H 2 S partial pressure (PH 2 S), temperature and pH. The sulphide layer performed better protective property in the acid solution than that in the neutral solution under 1 bar H 2 S at ambient temperature [8,11].…”
