Evaluation of the inhibitory effect of methylene blue dye on the corrosion of aluminium in hydrochloric acid

A Study into the Corrosion Inhibition of Carbon Steel in Acidic Medium Using Eco-Friendly Compounds

“…These results are consistent with values of fraction electrons transferred from aminobenzylpenicillin and cefixima inhibitors to metal iron ( ) which were calculated according to equation (9) ………………. (9) The parameters which were used in the calculation are defined in detail in previous reports [92][93][94][95][96][97] .…”

“…as well as aromatic rings which have enough electron density to share with empty orbitals on the metal 8 . Organic heterocyclic compounds containing S and N atoms are the most effective to decrease the corrosion processes and retard the anodic and / or cathodic reactions and are therefore classified as good corrosion inhibitors 9 .Unfortunately, although these organic inhibitors are highly effective towards their influence on the half-reactions, and comparable with the inorganic compounds such as nitrite and chromate, etc. which may also be used as inhibitors.…”

Corrosion Inhibition of Triazinedithoil for Aluminum Alloy in Hydrochloric Acid Solution

“…The thin, adherent and compact oxide film formed on aluminum surface can protect the metal in various environments [2][3][4][5]. But the oxide film is amphiprotic and the metal dissolves readily in acidic or basic solutions [6]. Mineral acid, mainly hydrochloric acid is widely used to remove oxide in several industrial processes such as acid pickling, acid cleaning and oil well acidizing.…”

“…Adding a corrosion inhibitor is an important and effective method to decrease the rate of the metal dissolution in such solutions. Many organic compounds such as aliphatic and aromatic amines as well as nitrogen heterocyclic molecules can serve as corrosion inhibitor effectively [2,[6][7][8][9][10].…”

Effect of Copper and Silicon Carbide Content on the Corrosion Resistance of Al-Mg Alloys in Acidic and Alkaline Solutions

“…The accelerating action of mercaptoacetic acid on aluminum corrosion is ascribed to a catalytic effect on the hydrogen evolution reaction. Oguzie et al [14] studied the effect of addition methylene blue (MB) dye on the electrochemical corrosion of aluminum in HCl solutions using gravimetric techniques at 303 and 333 K. The results indicate that MB acts as an inhibitor in the acidic corrodent. They also estimated the reaction rates and activation energies for different solutions with and without inhibitors.…”
