“…Over the years there have been many reports on the corrosion behaviour of metals in soil. For most part, however, these studies have been concerned with underground structures made from ferrous alloys 4–13. Much less is known about the corrosion behaviour of nonferrous metals in soils 14, 15.…”

Corrosion of different materials (Cu, Al, Al-Cu and C-steel) in soil solution was evaluated at ambient temperature using various techniques. The weight loss of the studied materials varied exponentially with time. Kinetic data revealed that the corrosion of Cu and Al-Cu are diffusion controlled while Al and C-steel show gradual change from diffusion control to charge transfer control. Nonferrous materials have better durability factors than C-steel. Good consistency between the data obtained from EIS and PDP measurements was observed. SEM showed a biogenic corrosion layer with density that depends on the metal type. Correlation between corrosion rates and the estimated soil solution corrosivity was obtained.

In latest years, various techniques and chemicals have been used for the control of microbial influenced corrosion (MIC) of metals. The application of botanicalbased biocides is one of the effective and practical techniques in the fight against MIC. In the present study, the role of aqueous extract of ginger (Zingiber officinale) (GIE) as green biocide to control MIC of mild steel 1010 (MS) in a cooling water system was investigated. Biocorrosion behavior of Bacillus thuringiensis EN2 on MS and its control by GIE was analyzed by electrochemical measurements. Polarization, electrochemical studies (ES), weight loss measurements (WL), and surface analysis (XRD, X-ray diffraction spectroscopy, and FTIR, Fourier transform infra-red spectroscopy) were performed under various incubation periods up to 4 weeks. We observed that EN2 forms a thick biofilm on the MS metal surface at the end of the incubation period and the WL significantly increased to 993 mg at fourth week when compared to the initial immersion period (194 ± 2 mg). In contrast, with addition of GIE, WL was reduced about 41 ± 2 mg over biotic system (993 ± 2 mg). GC-MS analysis confirmed the adsorption of active component of GIE (b-turmerone) on the metal surface as a protective layer to prevent the biofilm formation and thus leads to reduction of corrosion. The optimum 20 ppm of GIE was found to be effective corrosion inhibition efficiency which was about 80%. From the results of WL, ES, XRD, FTIR, and GC-MS, GIE was identified as biocide and thus inhibits the bacterial growth on MS metal surface and it leads to control MIC. XRD showed that the GIE with EN2 resulted in less formation of corrosion products over biotic and abiotic systems. Overall, this research first shed light on the antibacterial activity of GIE inhibiting biofilm formation, thus reducing the corrosion of MS in cooling water systems.

The paints are used extensively in various fields, especially for the protection of the oil installations such as the storage reservoirs of crude oil. Reducing possession cost and applying the new hygiene and security standards imply the necessity to deepen the knowledge of the physico-chemical processes of ageing coatings in the first stage and their impact on the corrosion of the substrate.The tests have been carried out on a primer, and on painted steel plates completely immersed in a 3% NaCl solution. The survey of the water absorption and the kinetics deterioration of the paints have been achieved especially by means of electrochemical impedance spectroscopy under the test of salt spray. The barrier weakness of the primer paint, due to the existence of two capacitive loops observed on the Nyquist's diagrams has been put in evidence. While the study of the resistance of the complete system by the test accelerated in the salt spray shows that the system of painting presents a good resistance up to 196 hours, which is equivalent to 8 years of exposure.
