“…New corrosion inhibitors with minimal environmental impact, often called green or eco-friendly, have become increasingly desirable and essential 10 – 12 . The most promising alternative for preventing aluminum from corroding in acidic solutions are drugs since they are typically derived from biological sources, exhibit strong inhibition efficiency at low concentrations, and are naturally biodegradable 13 – 15 . Hamza et al 16 use the weight loss method to examine the phenylephrine drug's adsorption and performance characteristics for corroding Al (2024) alloy in 1.0 M HCl.…”

Aluminum–silicon alloys have become a preferred option in the automotive and aerospace industries thanks to their fault-tolerant process ability and reasonable static characteristics at relatively affordable costs. This study aimed to investigate the use of favipiravir (FAV) drug as a biocompatible and eco-friendly inhibitor to protect aluminum alloy (AlSi) surface in an aggressive acid environment (1.0 M HCl). The electrochemical measurements declare that FAV is categorized as an inhibitor of mixed type with a cathodic effect. At 100 ppm, FAV had the highest inhibitory efficiency (96.45%). FAV is associated with lower double-layer capacitance values and more excellent charge-transfer resistance. These results show that AlSi corrosion in 1.0 M HCl is reduced in the presence of FAV. The Langmuir model is well-suited to the FAV adsorption behavior (R2 ≈ 1). Chemisorption is the primary adsorption in this environment. The theoretical calculation studies corrosion inhibitors' molecular structure and behavior. Different quantum chemical properties of the FAV have been calculated, including energy difference (ΔE), softness, global hardness, and energy of back-donation depending on the highest occupied and lowest unoccupied molecular orbitals. In addition, Mulliken and Fukui’s population analysis and the Molecular Electrostatic Potential map represent the electron distribution and the molecule’s active centers. Experimental findings and quantum chemical computations matched, and FAV is recommended as a green corrosion inhibitor.

“…Aluminum and its alloys are extensively used in industry because they combine good physical properties, adequate mechanical performance, and quite good resistance to uniform corrosion. Aluminum alloys are widely applied in aircraft, automotive, railway, marine and construction industry [3]. In industrial sector, fouling mitigation is greatly essential and indispensable requirement [4].…”

The fouling behavior of Alloy 6061 aluminum in artificial seawater in the presence of Boswellia serrata extract was investigated. Fouling is one of the major issues that occurred commonly in the marine environment. Experiments were conducted to develop a model for fouling propensity. A response surface method was used to develop a model to predict fouling behavior. The model predicts the effect of the variables on fouling in artificial seawater medium in the presence of B. serrata extract. The experimental variables chosen were temperature, flow rate and time. Performance of the regression model calculated by the response surface methodology was verified with the analysis of variance technique. The model equation that was proposed using the response surface methodology showed good agreement with the experimentally obtained data.

In this article, a novel and facile method is used to construct superhydrophobic surfaces on aluminum alloys. A solution of aluminum chloride hexahydrate and N-dodecyltrimethoxysilane (DTMS) in ethanol was used as the electrolyte solution. The hydrolysis of DTMS was accelerated during the electrodeposition process, and the hydrolysate was bonded to a pretreated aluminum surface. The prepared aluminum alloy sample exhibits both superhydrophobicity (the surface water contact angle reached 155°) and excellent corrosion resistance. The inhibition efficiency of this sample is as high as 99.9% in 3.5 wt % NaCl solution, which remains at 98% even after 30 days of immersion. Thus, our fabrication can be well applied to the field of marine corrosion protection. Therefore, the working mechanism was discussed by confocal Raman microspectroscopy (CRM). In addition, the investigation by CRM and electrochemical impedance spectroscopy (EIS) also indicates that superhydrophobic samples show good stability in NaCl solution. The fabrication method can inspire new ideas for the construction of superhydrophobic aluminum alloys in the marine environment.
