“…The values of Cdl are judged to be lower than those of the blank values, confirming the adsorption of the inhibitor onto the metal surface, forming an electronic double layer [45]. These results are in good agreement with those obtained by polarization, where fenugreek extract proves to be a good inhibitor for aluminum in 1 M HCl with an efficiency of 83.79% in the extract with ethanol, 85.87% for the extract with DCM and 72.66% for the extract with pentane at 1400 ppm (Table 3).…”

The corrosion inhibition of aluminum by the extract of Trigonellafoenum-graecum L was studied in a hydrochloric acid 1 M solution using electrochemical polarization measurements and electrochemical impedance spectroscopy (EIS). Three organic solvents, pentane, dichloromethane (DCM) and ethanol, of different polarities, were tested. An inhibition efficiency of 86.6 %, 84.41 %, and 75.77 % was obtained by the addition of 1400 ppm of the extract using three solvents: DCM, ethanol and pentane, respectively. The potentiodynamic curves show that the decrease of aluminum corrosion in the presence of the fenugreek extract in a HCl 1 M solution mainly acts by a mixed process with an anodic tendency for both extracts with ethanol and with pentane; on the other hand, the extract with DCM showed a cathodic tendency. The temperature effect on the corrosion of aluminum indicates that the inhibition efficiency of the natural substance decreases with an increase in temperature. The inhibition efficiency values obtained from the polarization curves are in good agreement with those of EIS.

“…The values of increase with the growth of inhibitor concentration while Cdl values are decrease. The increase of values may suggest the formation of a protective layer on the electrode surface [24]. The charge transfer resistance values (RT) were calculated according to the difference between impedance values at lower and higher frequencies.…”

The essential oil of Artemisia herba alba has been extracted and tested as an inhibitor of lead corrosion in 0.1 M Na2CO3 medium, using stationary and transient electrochemical techniques. The results obtained show that the essential oil of Artemisia reduces the corrosion rate. The effectiveness of inhibition increases with the oil concentration to reach 77 % with 2000 ppm. The effect of temperature was also studied.

“…Most of the efficient corrosion inhibitors used in industries is organic compounds having multiple bonds and hetero atoms like nitrogen, oxygen, sulphur, through which they are adsorbed on the metal surface. They function by interfering with either the anodic or cathodic reactions or both (Vinod Kumar et al, 2010).…”

The present study was undertaken to find out the phytochemicals present in Bougainvillea glabra bracts extract and to compare the corrosion inhibition efficiency between B.glabra Pink, Orange and White coloured bract extract on mild steel in 1N HCl. Phyto chemical analysis showed the presence of alkaloids, flavonoids, phenolic compounds and tannins in the extract as confirmed by implying different qualitative tests specified for these phytochemical. Corrosion rate, inhibition efficiency, FTIR analysis was determined. The corrosion of mild steel in 1N HCl acid media was significantly reduced upon the additions of BG bract extracts. The inhibition efficiency increased with the increasing concentration of the inhibitor. Maximum inhibition efficiency was observed at an optimum concentration of 2 % v/v.
