“…There was no significant change in grain size between the holding time of 10 min and 60 min, which indicated that the deformation storage energy was not released completely at the beginning. With the holding time extension, it had enough driving force to make the grain grow sequentially [15].…”

“…Especially in recent years, the performance of aluminum foil had improved to a certain extent, and the application scope was gradually expanded. The high level of cold reductions of aluminum foil was always subjected to final annealing and obtained a large scale of cube components [14][15][16]. However, abnormal grain growth behavior was Materials 2022, 15, 1395 2 of 11 obviously and commonly observed in annealing aluminum foil.…”

To clarify the microstructure, grain size, and recrystallization behavior during different annealing processes with controlled heating rates, the aim of this study was to investigate the effect of residual deformation energy after cold rolling and critical heating rate on cubic texture components, and grain growth behavior of aluminum plate, which was subjected to severe deformation. The experimental results revealed that the stored energy can be inferred from a calculation that fast annealing (FA) for 30 s was 2.2 times as large as slow annealing (SA) at 320 °C, which provided the driving force for grain growth during subsequent heating and resulted in a significant coarsening of grains in the FA process. In contrast, the intensity of cubic texture in SA was significantly higher than that in the FA process. A critical heating rate of 50 °C/min had been obtained to produce a homogeneous microstructure and strong cubic texture during the annealing processes with controlled heating rates and was verified by experiment. The relationship of Δηsur > 0.02ηb was as a criterion used to determine whether abnormal grain growth happened in aluminum foil, while the grain size exceeded the thickness of aluminum foil by examined calculation.

“…Anodization is a well-known approach for producing nano-structures on a variety of metallic materials, for example on aluminium (Al), due to the comparatively cost-effectiveness of the process and simple experimental setup (Runge 2018). The nano-structures developed via this technique noticed a wide variety of energy storage applications (Nualsing et al 2021), and applications of water treatment related to the solar energy (Kaur et al 2018). Improvements in photo electrochemical, thermal, optical, and mechanical characteristics cab be achieved at low cost by modifying structural parameters of the resultant nanostructures via anodization.…”

Development of nano-porous structures utilizing a single step of anodization technique is well recognized as a cost-effective and straightforward approach for several applications. In the current work, anodized alumina was developed with nano-porous structure by utilizing oxalic acid as an electrolyte with a continuous voltage of 40 V. The formed nano-porous structure was subjected to desalination application because of its high absorbance of broadband solar spectrum energy. The desalination setup consists of two solar stills namely conventional and modified. The developed structure is placed in the modified still to examine its performance. It was observed that the structure distributing heat to surrounding water by absorbing photon energy from the sun through the nanopores and giving an efficient pathway to the water vapors for developing effective desalination. The nano-porous structure having ~ 45 nm average diameter. Furthermore, the band gap energy of nano-porous structure was found to be ~ 2.5 eV (Absorption Spectrum Fitting) and ~ 2.8 eV (Tauc plot). The nanoporous structure possess the visible light spectra in solar region which helps the band gaps of nanoporous structure to provide an additional supply of energy for generating more water to evaporate. Moreover, the urbach energy of the structure is 0.5 eV which reveals less defects in the modified still. The overall distillate yield of modified still was increased to 21% in contrast to conventional. Water quality analysis was also carried out before and after the desalination experiments and the results were within acceptable limits set by World Health Organization (WHO).

“…Anodizing is an electrochemical method that is widely used in industry for surface functionalization of aluminum and its alloys. By anodizing processes, aluminum oxide layers are produced onto aluminum surface in order to achieve a wide variety of properties such as protection against weathering, 1,2 strengthening of the resistance to abrasion, increasing of superficial hardness, 3,4 achievement of new surface characteristics (color, reflectivity, insulation), improvement of adhesive bonding, and specially the improvement of corrosion resistance. Corrosion testing plays a crucial role in the qualification and certification of materials for technological applications.…”

In this work, the output of different accelerated tests on anodic aluminum oxide (AAO) coatings developed on AA5005 aluminum alloy (sulfuric acid bath and hydrothermal sealing) has been investigated. In particular, three corrosion testing methods, namely neutral salt spray test (NSS), acetic acid salt spray (AASS) and prohesion test, have been performed on the sealed AAO-coated panels in order to investigate the reliability of the obtained results to the electrochemical impedance ones. NSS and prohesion testing results are found to align with findings from electrochemical impedance spectroscopy (EIS). The acetic salt spray test proved highly corrosive, causing rapid depletion of the oxide layer's protective capabilities, as indicated by the EIS analysis. These results seem to be underestimated by optical image analysis.
