“…This result can be interpreted in a way that the temperature rise up induce desorption of some adsorbed components of the extracts from the surface. It is indeed consistent with the proposed physisorption mechanism [14].…”

The inhibitory effect of the crude ethyl acetate extract of Saccocalyx satureioides was estimated on the corrosion of carbon steel (X52) in 1 M HCl solution sing weight loss measurement, potentiodynamic polarization, electrochemical impedance spectroscopy and scanning electron microscopy techniques. Potentiodynamic polarization curves indicated that the plants extract behaves as a mixed-type inhibitor. The adsorption of the inhibitor on the carbon steel surface was found to follow Freundlich adsorption isotherm. The free energies, enthalpies and entropies for the adsorption and dissolution process were discussed in details. The inhibiting action increases with increasing concentration of the extract. The results obtained show that the extract of the aerial parts of Saccocalyx satureioides could serve as an effective corrosion inhibitor of carbon steel (X52) in hydrochloric acid medium.

Corrosion Inhibitors, Principles and Recent Applications

View full text Add to dashboard Cite

Corrosion of metals is a serious environmental problem. Most of the corrosion inhibitors are synthetic chemicals that are hazardous to environments and expensive. Today, there has been an increasing search for green corrosion inhibitors, due to the toxicity of some inhibitors. Green corrosion inhibitors are biodegradable and free of heavy metals or other toxic compounds. There is an intensive effort underway to develop new plant origin corrosion inhibitors for metal subjected to various environmental conditions. Salts of rare earth elements can be also used as inorganic alternative nontoxic corrosion inhibitors. Sol-gel coatings can be recommended as green protective films for metal corrosion. The origin of sol-gel process, its advantages and limitations, and the type of coating method are presented in this chapter, as well as a brief summary of recent literature concerning the use of hybrid inorganic-organic sol-gel and nanostructured sol-gel protective coatings for metal corrosion in different media.

Ethyl acetate extract (EAE) and butanolic extract (BE) of Thapsia villosa were investigated as corrosion inhibitors of Carbon Steel (CS) in 1 M H 2 SO 4 using electrochemical impedance spectroscopy (EIS) techniques, potentiodynamic polarization and weight loss measurements. The effect of temperature on the corrosion behavior of CS was studied in the range of 20-40°C. The experimental results show that EAE and BE are good corrosion inhibitors and the protection efficiency increased with increasing concentration of the extracts, but decrease with rise in temperature. The EAE and BE act as a mixed types inhibitors. The adsorption of extracts on CS surface follow Langmuir isotherm. The apparent energies, enthalpies and entropies of the dissolution process were discussed.
