Corrosion inhibition of mild steel in hydrochloric acid solution by a mercapto-triazole compound

Synthesis and characterization of new quinoxaline d erivatives of 8- hydroxyquinoline as corrosion inhibitors for mild s teel in 1.0 M HCl medium

“…The effect of temperature on mild steel gave us in general some information on the adsorption [41][42][43][44][45][46]. For this reason, we studied the change of the corrosion rate with the temperature in 1 M HCl solution during 1 h of immersion; both in the absence and presence of Q-CH 3 NHyQ and Q-HNHyQ in the temperature range from 298 to 328 K, the obtained results are shown in the Figures 8-10.…”

Study of Temperature Effect on the Corrosion Inhibition of C38 Carbon Steel Using Amino-tris(Methylenephosphonic) Acid in Hydrochloric Acid Solution

“…It was found that few inhibitors with acid-metal systems have specific reactions that are still effective at high temperatures as (or more) they are at low temperatures [7,8]. A large number of investigations have studied the temperature effects on acidic corrosion and corrosion inhibition of iron and steel in HCl and H 2 SO 4 solutions [9][10][11][12][13][14][15][16][17].…”

sym-Trisubstituted 1,3,5-Triazine Derivatives as Promising Organic Corrosion Inhibitors for Steel in Acidic Solution

“…The adsorption of T3Q, T3AMPy and T3EA can be explained by the gradual replacement of water molecules with high dielectric constant by T3Q, T3AMPy and T3EA molecules with low dielectric constant. As immersion time and concentration increased, the thickness of the adsorbed layer increased leading to a decrease in the electrical capacitance [33]. The results of increasing of Rct and the decreasing of Cdl values suggests that T3Q, T3AMPy and T3EA blocking the active sites on the steel surface via adsorption [34], which could be confirmed that a protective layer formed at the steel/solution, which enhances the corrosion protection performance of steel [35].…”
