Inhibition Mechanism of Pitting Corrosion of Nickel in Aqueous Medium by Some Macrocyclic Compounds
Anodic polarization of nickel was studied by potentiostatic technique in neutral media in presence of two macrocyclic ligands. Pit initiation was detected by measuring pitting potential, Ep and the charge transfer, Q during the anodic polarization. Initiation of pitting and Q were found to be dependent on the structure and concentrations of inhibitors. Under steady state conditions, the inhibit...
متن کاملInhibition of acidic corrosion of iron by some Carrageenan compounds
The corrosion inhibition of some sulfated water soluble natural polymer (carrageenan) compounds on the corrosion of iron in 1M HCl was studied using weight loss and galvanostatic polarization measurements. The percentage inhibition efficiency was found to increase with increasing concentration of inhibitor and with decreasing temperature. The inhibitive action of these compounds was discussed i...
متن کاملNew possibilities of metal corrosion inhibition by organic heterocyclic compounds
It is shown that many heterocyclic organic compounds, e.g., various azoles, are capable of adsorption on metals with formation of strong bonds with the surface. The approach based on the linear free energy relationship (LFER) principle offers a description of the efficiency of corrosion inhibition by these compounds and provides an understanding of the nature of chemical bonds formed by an orga...
متن کاملApplication of Electrochemical Noise to Investigate Corrosion Inhibition Properties of Some Azole Compounds on Aluminum in 0.25 M HCl
The corrosion inhibition properties of the benzothiazole BTH and benzotriazole BT inhibitors on the aluminum in 0.25 M HCl solution were studied. Electrochemical impedance spectroscopy EIS, electrochemical noise EN and potentiodynamic polarization techniques were used to investigate the inhibition properties of the inhibitors. Scanning electron microscope SEM was also utilized in order to inves...
