“…These extracts are a mixture of various phytochemical constituents (alkaloids, flavonoid, terpenoids, steroids, and amino acids, …. ), contains several heteroatoms such as nitrogen, oxygen, sulfur, and aromatic rings and/or functional groups, which they can be adsorbed on metal surface through coordinate covalent bond or electrostatic interaction [15,16]. Various studies has been reported recently regarding the inhibition efficiency of different plants extract against steel corrosion: Holoptelea integrifolia leaves [9], lychee fruit [17], Curcuma longa extract [18], Aloe Vera leaf [19], Thymus Vulgaris [20], Egyptian licorice [21], Coreopsis tinctoria [22].…”

The current investigation presents the corrosion activity of Elaeoselinum thapsioides (BEET) butanolic extract in 1 M HCl as a novel green source of corrosion inhibitor, and it's synergetic effect with another butanolic extract of Reutera lutea (BERL), whose belongs to the Apiaceae family. Weight loss measurements, potentiodynamic polarization and electrochemical impedance spectroscopy (EIS) measurements have been done to study the inhibition efficiency. The obtained results showed that the inhibition efficiency of BEET alone increase with concentration and reached a value of 82% at 900 ppm. However, the maximum protection efficiency was more than 92% with the combination of BEET and BERL inhibitors. The rise of temperature caused a significantly decreased of inhibition efficiency. The potentiodynamic polarization results revealed that the extract functions as mixed-type inhibitor with predominance at anodic domain, and the adsorption process of the extract follows Langmuir isotherm. In addition, EIS shows that increasing the concentration of the inhibitor leads to an increase of the charge transfer resistance and reducing the double layer capacitance. The synergistic factor (S) was used to investigate the synergistic behavior of the selected inhibitors.

“…Optical microscope test, Figure 9, revealed that when a smooth surface of aluminum alloy is immersed in 1.0M HCl solution, in absence of AS extract, corrosion pits were created on the surface of the aluminum due to aggressive attack of the HCl solution [1,56]. A rough surface with flakes of dark color is observed, Figure 9(a), which indicates deposition of corrosion products and/or chloride ions on the surface.…”

“…Corrosion resistance of aluminum is due to the formation of a thin and protective, naturally formed oxide film on its surface [1,2]. However, when aluminum is exposed to acidic environment as a result of acid pickling solutions, chemical etching, industrial cleaning or scale dissolution, the oxide film dissolves resulting to significant mass loss of aluminum [3].…”

Inhibitive impact of Akuamma seed (AS) extract toward 1.0M HCl corrosion of aluminum was examined using response surface methodology (RSM). Gravimetric (weight loss), potentiodynamic polarization and electrochemical impedance spectroscopy techniques were used in the corrosion inhibition process. In all the method used, the seed extract acted as good corrosion inhibitor of aluminum in 1.0M HCl solution. Optimal inhibition efficiency of 72.6% was obtained at optimum inhibition concentration of 1.2g/l, temperature of 304.19k and maximized time of 11.53hrs. It showed that the plant extract has excellent inhibitive properties for the corrosion inhibition process. The values of kads are relatively small indicating that the interaction between the adsorbed extract molecules and aluminum surface is a physical process. The (AS) extract protects aluminum against pitting corrosion. The level of protection increases with increase extract concentrations. The extract inhibited both cathodic and anodic reactions and acted as mixed-type inhibitor.
