“…Their experimental results demonstrated that the distribution of bacteria was independent of the coating combinations, and the bacteria were found to adhere preferentially on the iron corrosion products in coating defects, thus leading to localized corrosion underneath the polymer coatings (Al-Darbi et al, 2002). Jones-Meehan et al (1992) and Miller et al (1964) used energy dispersive X-ray spectroscopy (EDS) to investigate the change of polymercoated steel exposed to mixed communities of marine bacteria. The breaching of epoxy, nylon, and polyurethane coatings on the surface of steel coupons were detected by the EDS spectra.…”

Biocorrosion has been considered as big trouble in many industries and marine environments due to causing of great economic loss. The main disadvantages of present approaches to prevent corrosion include being limited by environmental factors, being expensive, inapplicable to field, and sometimes inefficient. Studies show that polymer coatings with anticorrosion and antimicrobial properties have been widely accepted as a novel and effective approach to prevent biocorrosion. The main purpose of this review is to summarize up the progressive status of polymer coatings used for combating microbial corrosion. Polymers used to synthesize protective coatings are generally divided into three categories: (i) traditional polymers incorporated with biocides, (ii) antibacterial polymers containing quaternary ammonium compounds, and (iii) conductive polymers. The strategies to synthesize polymer coatings resort mainly to grafting antibacterial polymers from the metal substrate surface using novel surface-functionalization approaches, such as free radical polymerization, chemically oxidative polymerization, and surface-initiated atom transfer radical polymerization, as opposed to the traditional approaches of dip coating or spin coating.

A conventional and two high copper amalgams were tested in 0.5% aqueous solutions of acetic, formic, lactic and succinic acid. The corrosion behavior of the amalgams in the different solutions was evaluated by analyzing the soluble corrosion products using an atomic absorption spectrophotomeler every month during a 6‐month experimental period. The high copper amalgams showed a high dissolution rate in formic and lactic acid solutions from the initial stages of immersion when compared to the conventional. Later a marked decrease of the dissolution rate could be observed but it still remained at high levels. In acetic acid the amounts of elements dissolved from high copper amalgams were much less. Conventional amalgam released much smaller amounts of elements in almost all solutions tested except in the case of silver in lactic acid. Finally, in succinic acid solution, the amounts of elements dissolved were unexpectedly small considering the low pH of the solution and the dissolution rates of the amalgams in the other organic acid solutions.

“…The oxygen concentration cells formed between the zones covered by the microorganisms and the uncovered zones as a consequence of the fungus respiration have been reported by Miller et al [26]. Iverson et al [27] reported the presence of tubercles on the bottom of jet fuels tanks containing sulfate reducing-bacteria which corrode materials through the formation of electrochemical oxygen concentration cells, and cathodic depolarization due to the bacterial sulfate reducers.…”

Aluminum and its alloys are central materials for the aircraft industry. Aluminum alloys (AA) 7075 and 2024 are widely used both in the structures and in brittle sections of the airplanes. The presence of the alloying elements in these metals makes them susceptible to localized corrosion at the same time vulnerable to bacterial attachment. A great number of reports on aircraft deterioration are related to microbial growth by contamination inside fuel storage tanks and aircraft wing tanks; this phenomenon is known as microbiologically influenced corrosion (MIC). As expected, corrosion and biocorrosion increase maintenance costs and time of the aircraft in the hangar. Therefore, the growing interest is to shed light on these issues and develop future inhibition methods. In this chapter, we will give an overview of microbiologically influenced corrosion associated with AA 2024 and 7075 by consortia and bacteria. Three mechanisms of biocorrosion in aluminium alloys have been described. In addition, some alternatives methods to battle the effect of biocorrosion will be shown, these methods are based on green compound which blocking of attached of bacteria and promote the detachment of biofilm, being these a tendency of the last innovation way to inhibit this kind of phenomenon.
