“…The resulting micrograph revealed that the surface was strongly damaged owing to corrosion in the absence of the inhibitor, but in the presence of the inhibitor there was much less damage on the surface. This was attributed to the formation of a good protective film on the mild steel surface (Migaheda et al, 2011).…”

The efficiency of new water soluble composite namely, poly (vinyl alcohol-o-methoxy aniline) PVAMOA has been studied for corrosion inhibition of mild steel in 1 M hydrochloric acid (HCl). Corrosion inhibition was investigated using weight loss, potentiodynamic polarization and electrochemical impedance studies. The kinetic and thermodynamic parameters for mild steel corrosion and inhibitor adsorption respectively, were determined and discussed. The adsorption of PVAMOA on the mild steel surface obeyed Langmuir followed by El-Awady adsorption isotherm. The adsorption of the composite was established by scanning electron microscope (SEM).

“…Figure shows the time dependence of the open circuit potential, E OC , for DP steel monitored over a period of 120 min in quiescent 0.5 M H 2 SO 4 solution containing various I − ion concentrations. In inhibitor‐free sulfuric acid solution, the E OC changes quickly towards negative values, indicating the initial dissolution process of the pre‐immersion, air formed oxide film and the attack on the bare metal . A steady‐state potential (vs. SCE) is readily attained corresponding to the free E OC of the DP steel .…”

Potassium iodide was studied for its corrosion inhibition property on the corrosion of dual‐phase steel in 0.5 M sulfuric acid at 25°C by potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) techniques. Scanning electron microscopy was used to characterize the steel surface. The inhibition efficiency increases with the concentration of iodide ions. The thermodynamic parameters Kads and ΔG0ads are calculated and discussed. The probable inhibitive mechanism is proposed from the viewpoint of adsorption theory.

“…This behaviour reflects the dissociation of free metal initial process before the immersion of the thin oxide film that formed in air and later deposited on the metal 31 . In the presence of cefixima and aminobenzylpenicillin drugs, the OCP values (Table 1) drift slightly to positive direction as a result of the formation of the protective film on the surface of the carbon steel electrode 32 . Thus, in all inhibited cases, at first the OCP values increase to more noble values and later reach a steady state rate with time (at this state the oxidation current is equal to the reduction current and reaches a state of equilibrium 33 ).…”

The corrosion inhibition effects of cefixima and aminobenzylpenicillin drug inhibitors in 0.05M deaerated sulfuric acid solution for carbon steel have been studied by using electrochemical techniques and quantum chemical calculations as well as scanning electron microscope (SEM). It is observed from the experimental findings that both compounds perform as good inhibitors and behave according to mixed type inhibitor in terms of their inhibitory action. Additionally, it was found the percentage of corrosion inhibition become maximal when the concentrations of the cefixima and aminobenzylpenicillin inhibitors are increased. The influence of temperature on the corrosion of carbon steel has been investigated and the activation energy values estimated. The corrosion efficiency decreases with increasing the temperature range. The parameters of thermodynamic have been determined and indicate that the adsorption mechanism follows the Langmuir isotherm model and forms a protective layer on carbon steel surface electrode, which was characterized by scanning electron microscope measurements, to prevent a corrosion process. Quantum chemical calculations have been performed to provide evidence for corrosion inhibition according to the chemical structures of the cefixima and aminobenzylpenicillin drug inhibitors.
