“…In theory, as long as two materials have not contacted each other, a corrosion cell will not initiate. Zhang et al [ 27 ] investigated the galvanic coupling of graphite/epoxy composites and magnesium in seawater. They also suggested that the simplest way to prevent galvanic coupling is electrical isolation of carbon fibers and metal using organic fiber plies and sealer coatings.…”

Fiber metal laminates (FMLs) based on carbon and glass fibers with aluminum as construction materials raise questions to the formation of corrosion. This article addresses the problem of the corrosion resistance of aluminum with glass and carbon fibers and with titanium layers. The laminates are exposed to the NaCl environment. Holes and half-holes are made to identify the effect of carbon-fiber layers to determine the corrosion behavior depending on the applied surface treatment. The dominant forms of corrosion occurring on the aluminum layer surface are pitting and intergranular corrosion. In addition to that, galvanic corrosion is treated in the laminates containing carbon fibers.

“…29 Stirring of Mg during the reaction is an important process and helps to remove the oxide layers and reduces the reaction time (<1 h), but it is not favored for large-scale reduction using Mg turnings because the glass reactor can be damaged by abrasion, whereas slower stirring is not effective with large-scale reductions. 30 Acid treatment is another method to remove the oxidized layers from Mg surface, 31 by which Mg is activated through increasing the active sites on the Mg surface. 30 In this work, glacial acetic acid was used as the activator because it is water-free, which improves the reaction efficiency, easy to handle, and environmentally friendly.…”

Optimizing Reductive Degradation of PAHs Using Anhydrous Ethanol with Magnesium Catalyzed by Glacial Acetic Acid

Targeted degradation of individual polycyclic aromatic hydrocarbon (PAH) constituents like anthracene, may offer cost effective and efficient cleaning of coal tar-contaminated sites. Thus, a reductive degradation procedure of anthracene using activated magnesium with anhydrous ethanol at room temperature was developed and optimized. To determine the optimum conditions for anthracene, such as effective magnesium concentrations, glacial acetic acid volumes, and exposure time for the anthracene reduction, the experiments were designed using the response surface methodology based on the central composite design. The design also minimized the number of experiments. The main product from anthracene reduction is 9,10-dihyrdoanthracene. Optimum conditions for 98% degradation capacity of anthracene (2.80 × 10 –3 mmol) were 30 mg of Mg powder (1.20 mmol), 60 μL of glacial acetic acid (1.05 mmol), and 30 min exposure time. When the optimized method was tested on the coal tar specimen, twice as many reagents (i.e., Mg and glacial acetic acid) were required to obtain a 90% degradation of anthracene and fluoranthene from the coal tar. This method of using activated Mg and anhydrous ethanol selectively reduces PAHs in coal tar; in particular anthracene and fluoranthene are most efficiently removed.

“…Unfortunately, many AAs are susceptible to chloride ion attack, largely limiting their marine applications (Tseng et al , 2012; Sekularac and Milosev, 2018). Therefore, it is necessary to greatly improve the corrosion resistance of AAs against ion attacking, and surface treatment methods have been widely implemented (Kosari et al , 2020; Zhang et al , 2017; Padash et al , 2020; Yabuki et al , 2019), such as anodizing, plating, conversion coating, polymer coating and micro-arc oxidation (MAO) coating. Particularly, MAO coating is of great interest due to its high electric insulation resistance and good adhesion (Ji et al , 2017; Cai et al , 2020; Zong et al , 2019).…”

Purpose Aluminum alloy is susceptible to chloride ion attack in sea water, resulting in pitting damage and hence serious security risks for the related applications. To improve the corrosion resistance of Al alloy, micro-arc oxidation (MAO) technology has been developed to produce a protective dense oxide layer on top of Al alloy. However, the mechanism of MAO-induced corrosion resistance is still not fully understood, particularly on local corrosion issue. This paper aims to focus on comprehensively studying the corrosion-resistance mechanism by a series of technologies. Design/methodology/approach The corrosion behavior of samples was studied by open circuit potential (OCP), potentiodynamic polarization (PDP), electrode impedance spectroscopy (EIS) and localized electrode impedance spectroscopy (LEIS) tests in NaCl solution. Findings The MAO-coated Al alloy shows a more positive corrosion potential and a higher corrosion current density compared to the untreated counterpart, indicating a significantly enhanced corrosion-resistance. The study of surface morphology and structure also suggest significantly enhanced corrosion-resistance due to the MAO treatment. Originality/value Based on the results, a new corrosion model was proposed to describe the influence of MAO treatment on the corrosion process and corrosion mechanism of Al alloy, providing insights on the design of the corrosion-resistance coating for metallic alloys in marine applications.
