Effect of 2-mercaptobenzothiazole on aciddissolution and hydrogen absorption of steel

Comparative Study on the Corrosion Inhibitive Effect of 2-Mecraptobenzothiazole and Na2HPO4 on Industrial Conveying API 5L X42 Pipeline Steel

“…This indication clearly denotes that Na2HPO4 acts as an anodic inhibitor for mild steel, which is a result that is also confirmed by the literature [75]. On the other hand, for the system Steel-WSS-MBT, the OCP shifts to negative values, indicating that the presence of MBT inhibits the cathodic reactions [76]. Finally, the presence of both Na2HPO4 and MBT into the WSS (Steel-WSS-Na2HPO4-MBT) results in OCP values more negative than those of Steel-WSS-blank and more positive than those of Steel-WSS-MBT.…”

Semiempirical investigation of the inhibition efficiency of thiourea derivatives as corrosion inhibitors

“…It has been reported that sulphur-containing inhibitors are useful in sulphuric acid solution, while N-containing inhibitors exert their best efficiencies in hydrochloric acid [4]. Thiourea (TU) and its derivatives have been studied as interesting organic inhibitors for corrosion especially for iron and steel for a long time [5][6][7][8][9][10][11][12][13][14][15][16]. It is observed that TU has a high inhibition efficiency at low concentration and loses its efficiency at a certain concentration.…”
