N,N 0 -Bis(phloroacetophenone)-1,2-propanediamine as corrosion inhibitor for steel in hydrochloric acid has been studied using electrochemical techniques and surface techniques. Results showed that the inhibition occurs through adsorption of the inhibitor molecules on the metal surface. The inhibition efficiency was found to increase with increasing inhibitor concentration and decreased with increasing temperature. Thermodynamic parameters for adsorption and activation processes were determined. Polarization data indicated that this compound acts as the mixed-type inhibitor and the adsorption basically obeys the Langmuir adsorption isotherm. The quantum chemical calculations were performed at the density functional theory level using B3LYP functional with the 6-31G (d,p).

“…To obtain a satisfactory impedance simulation of cerium oxide coated aluminum, it is necessary to replace the capacitor (C) with a constant phase element (CPE) Q in the equivalent circuit. The most widely accepted explanation for the presence of CPE behavior and depressed semicircles on solid electrodes is microscopic roughness, causing an inhomogeneous distribution in the solution resistance as well as in the double layer capacitance 44,45 . To corroborate the equivalent circuit, the experimental data are fitted to the equivalent circuit and the circuit elements are obtained.…”

In this study, cerium-based conversion coating was deposited on steel X52 by dip immersion method. Cerium oxide/hydroxide is an environmentally friendly conversion coating. The effects of immersion times and immersion temperatures on corrosion properties of cerium conversion coating on steel X52 were studied. Its corrosion resistance in 3.5 wt.% NaCl solution was investigated by means of electrochemical impedance spectroscopy, potentiodynamic polarization, and surface techniques. The coated samples showed a significant decrease in corrosion rate and corrosion current decreased with increasing immersion time up to 60 s. In addition, electrochemical impedance data showed that in the presence of cerium oxide conversion coatings, the charge transfer resistance of aluminum increased. The experimental results indicated that the corrosion resistance decreased with increasing the operating temperature. Surface morphology and its chemical composition were analyzed by means of scanning electron microscopy and energy dispersive spectroscopy.
