“…The fractality of some copper alloys’ behavior has been investigated in studies related to electrochemical corrosion [ 1 , 2 , 3 , 4 , 5 , 6 , 7 ] and signal analysis [ 18 ]. Also, multifractal analysis of corroded surface images has been performed for different materials [ 38 , 60 , 61 , 62 ]. Still, these studies have been performed using a smaller number of tools, among which are R/S rescaled analysis and MFDFA [ 50 ].…”

The fractal approach is one of the nondestructive techniques for analyzing corrosion’s effects on different materials. This article utilizes it to analyze the erosion–corrosion produced by cavitation on two types of bronze introduced into an ultrasonic cavitation field to investigate the differences between their behavior in saline water. The aim is to check the hypothesis that the fractal/multifractal measures significantly differ for the studied materials that belong to the same class (bronze) as a step in applying fractal techniques to distinguish between two materials. The study emphasizes the multifractal characteristics of both materials. While the fractal dimensions do not significantly differ, the highest multifractal dimensions correspond to the sample of bronze with Sn.

“…EN involves measuring the electrochemical transient noise produced by the corrosion process [131,132]. This is accomplished by measuring the potential noise of the potential difference between two identical electrodes or by tracking current differences between two similar electrodes using a zero resistance ammeter [133].…”

Almost every abiotic surface of a material is readily colonised by bacteria, algae, and fungi, contributing to the degradation processes of materials. Both biocorrosion and microbially influenced corrosion (MIC) refer to the interaction of microbial cells and their metabolic products, such as exopolymeric substances (EPS), with an abiotic surface. Therefore, biofouling and biodeterioration of manufactured goods have economic and environmental ramifications for the user to tackle or remove the issue. While MIC is typically applied to metallic materials, newly developed and evolving materials frequently succumb to the effects of corrosion, resulting in a range of chemical reactions and transport mechanisms occurring in the material. Recent research on biocorrosion and biofouling of conventional and novel materials is discussed in this paper, showcasing the current knowledge regarding microbial and material interactions that contribute to biocorrosion and biofouling, including biofilms, anaerobic and aerobic environments, microbial assault, and the various roles microorganisms’ play. Additionally, we show the latest analytical techniques used to characterise and identify MIC on materials using a borescope, thermal imaging, Fourier transform infrared (FTIR), atomic force microscopy (AFM), scanning electron microscopy (SEM), X-ray photoelectron microscopy (XPS), X-ray diffraction (XRD), optical and epifluorescence microscopy, electrochemical impedance spectroscopy, and mass spectrometry, and chemometrics.

“…Recently, aqueous monoethanolamine (MEA) solvent has been investigated for its feasibility for large-scale applications based on efficient energy consumption, removal capacity, and other cost-related studies. − In general, aqueous amine solvent is thermally stable, is highly selective, and has greater than 90% CO 2 capture efficiency; however, the corrosion potential of materials coming in contact with the solvent is a major operational concern in amine treatment plants because it may lead to structural integrity issue and failure. For example, carbon steel (e.g., S235) has unacceptable levels of corrosion failure in aqueous MEA . Also, aluminum alloys are corrosion resistant in the atmosphere; however, they often have poor corrosion resistance when they are submerged in aqueous solutions.…”

The aluminum corrosion rates are relatively high when the pH of the chemical stream is either below 4 or above 7.…”

Corrosion of additively manufactured (i.e., 3D printed) aluminum packing devices, developed to enhance heat and mass transfer in CO 2 absorption columns using amine-CO 2 scrubbing solutions, is investigated in this paper. The aluminum structures printed by selective laser melting with Al-10Si-0.3Mg feed powder are susceptible to corrosion in aqueous monoethanolamine, both fresh and used CO 2 -saturated solutions. The efficacy of corrosion-protective surface layers of aqueous polyether−ketone−ketone (PEKK) dip coating to provide amine corrosion resistance to the 3D printed aluminum structure is also evaluated. PEKK nanothick layers were coated on the corrugated surface of a 3D printed structure, identical to that of the intensified device, yielding 27 times higher corrosion resistance than the uncoated Al alloy surface. A systematic long-term electrochemical corrosion analysis revealed that a multilayer PEKK dip coating protocol enables protection of the 3D printed Al alloy surface in various CO 2 −monoethanolamine solutions.
