The corrosion inhibition of mild steel in acidic media by a new triazole derivative

The inhibition of carbon steel corrosion by lignin in HCl and H2SO4

“…Nevertheless, the protection of corrosion in HCl solution was better than that of H 2 SO 4 solution. The specific adsorption of anions having a smaller degree of hydration [2] and in this study, Cl -ions is possible to be more pronounced compared to SO 4 2-ions. As Cl -adsorbed on the metal surfaces, a negative charges created towards the solution consequently adsorb the cationic form of lignin molecules.…”

Comparative study of the inhibitive action between the bitter orange leaf extract and its chemical constituent linalool on the mild steel corrosion in HCl solution

“…The values of electrochemical impedance parameters obtained from fitting the experimental data of steel in 0.5 mol L -1 HCl 31 The electrical double layer capacitance varies as function of dielectric constant, compact layer thickness, electrode size, and electrolyte concentration. Due to the fact that CA extract contains huge amount of chemical constituents, the increase of Q dl values in its presence could be attributed to increasing dielectrics.…”

Inhibition of aluminum corrosion in 0.1 M Na2CO3 by Ricinus communis oil

“…The inhibition of materials corrosion by non-toxic organic inhibitors and heavy metal free is an encouraging solution that can effectively replace the use of chemical inhibitors [2][3][4] . The mechanism action of organic inhibitors is explained by physical and / or chemical adsorption on the metal surface 3,[5][6][7] . This inhibitive action depends on the physicochemical properties of the inhibitor atoms such as the functional group and the aromaticity as well as the presence of the heteroatoms [8][9][10] , without forgetting the nature of the surface, the temperature and the pressure of the reaction 11 .…”
