“…Corrosion rate was calculated from the Equation :

C o r r o s i o n r a t e = i_{c o r r} * A_{w} * 10 * 3.15 * 10^{7} / nFd

where i corr is the current density [A cm −2 ], A w − 56 g mol −1 of iron, F ‐ Faraday's constant (96 500 C mol −1 ), n = 2, d − density of stainless steel (7.93 g cm −3 ), 3.15*10 7 ‐ 1 year in seconds and 10 − is the factor used to obtain corrosion rate in mm/year …”

Six corrosion inhibitors based on dimeric quaternary ammonium salts (gemini surfactants) with a flexible/rigid spacer have been tested for stainless steel in 3 M HCl. Potentiodynamic polarization (linear polarization resistance, Tafel slopes) and electrochemical impedance spectroscopy have been used to determine the corrosion inhibition efficiency of the compounds. The results suggest that inhibitors act as anodic/cathodic inhibitors. The highest corrosion inhibition efficiency has been reached around the values of the critical micellar concentration for each inhibitor. Scanning electron microscopy has been applied to study the surface of the stainless steel samples. Theoretical studies of the inhibitors have been run based on density functional theory.

“…45,52,53 Besides, their shapes were imperfect due to the inhomogeneity and roughness of the electrode surface, the adsorbed inhibitor molecules on the electrode surface and the dispersion of frequency. 34,41 On the other hand, the diameters of these semicircles increased with an increase in inhibitor concentration. This indicated the enhanced protection of electrodes because of the increased coverage of inhibitors on the surface of electrodes.…”

Corrosion Inhibitors, Principles and Recent Applications

Organic corrosion inhibitors are one of the five ways, besides material selection, design, cathodic protection and coatings, to protect materials against corrosion. Corrosion is an ubiquitous phenomena that deteriorates all materials, metals, plastics, glass and concrete. The costs of corrosion are tremendous and amounts to 4.0% of gross domestic product (GDP) in USA. The similar losses of GDP are noted in all countries around the world. At this point of time, there is no way to completely stop the corrosion processes. Some new solutions can only slow this process. Organic corrosion inhibitors are widely used in industry because of their effectiveness at wide range of temperatures, compatibility with protected materials, good solubility in water, low costs and relatively low toxicity. Organic corrosion inhibitors adsorb on the surface to form protective film which displace water and protect it against deteriorating. Effective organic corrosion inhibitors contain nitrogen, oxygen, sulfur and phosphorus with lone electron pairs as well can contain structural moieties with π-electrons that interact with metal favoring the adsorption process. This review presents mechanisms and monitoring of corrosion, laboratory methods for corrosion study, relationship between structure and efficacy of corrosion inhibitions, theoretical approach to design new inhibitors and some aspects of biocorrosion.
