“…Benzamide can also be considered as an environmentally friendly inhibitor among many others that are currently receiving significant research attention in corrosion protection studies. [26][27][28][29][30][31][32][33] The results of the electrochemical tests obtained here are very much in agreement with the gravimetric tests. An appreciable effectiveness of the inhibitory properties of benzamide in the H 2 SO 4 test environments is achieved.…”

“…The semicircles are observed to be depressed to the z'(real) axis or showed slight irregularity which may be attributed to the roughness or nonhomogeneous nature of the metal surface [21][22][23][24]. The capacitance loop intersects the real axis at higher and lower frequencies.…”

3-Formylindole-4-aminobenzoic Acid: A Potential Corrosion Inhibitor for Mild Steel and Copper in Hydrochloric Acid Media

The corrosion inhibition efficiencies of Schiff base 3-formylindole-4-aminobenzoic acid (3FI4ABA) on mild steel (MS) and copper in 1.0 M HCl solution have been investigated using weight loss measurements, electrochemical impedance spectroscopy (EIS) and potentiodynamic polarization studies. The results show that inhibition efficiencies on both metals increase with increasing the concentration of the inhibitor. 3FI4ABA exhibited comparatively good inhibition towards mild steel in HCl medium even at low concentrations. The adsorption of inhibitor on the surfaces of the corroding metal mild steel and copper obeys the Langmuir isotherm. Polarization studies revealed that 3FI4ABA acts as a mixed-type inhibitor. Thermodynamic parameters (K ads , ΔG 0 ads ) were calculated using the Langmuir adsorption isotherm.

“…The potentiodynamic current-potential curves were recorded by polarizing the specimen to -250 mV cathodically and +250 mV anodically with respect to OCP at the scan rate of 5 mV/s. Electrochemical impedance spectroscopy (EIS), which gives early information about the electrochemical processes at the metal solution interface, has been used in many reports on corrosion studies [11][12]. The corrosion behavior of the specimen in annealed and aged condition was also investigated by EIS technique.…”

The corrosion behavior of aged and annealed sample of 18 Ni 250 grade maraging steel was investigated in varied conditions of concentration and temperature of sulphuric acid medium, using electrochemical techniques like Tafel polarization and electrochemical impedance spectroscopy (EIS). The results obtained from both the techniques are in good agreement. These results have shown increase in corrosion rate of aged specimen with increase in concentration and temperature of sulphuric acid. With increase in concentration of sulphuric acid from 0.025 M to 0.25 M the corrosion rate of annealed sample was found to increase, but there after in 0.5 M, 0.75 M and 1 M, the rate of corrosion decreases, indicating passivation of alloy surface at higher concentration of sulphuric acid. The corrosion rate of aged specimen was found to be higher than that of the annealed specimen. Similar observations are revealed by SEM images. The thermodynamic parameters like activation energy, enthalpy of activation and entropy of activation were calculated.
