“…Zhigao et al [51] worked on the atmospheric corrosion impacts on carbon steel (Q235) under varying exposure conditions such as volume and pH of rainfall, the concentration of sulfur (IV) oxide and chlorine, temperature, and relative humidity. It was observed that the exposure duration of the carbon steel to the atmospheric condition impacted the corrosion on the material.…”

Despite extensive work on improving atmospheric corrosion resistance in metals, i.e., steel and alloy, the corrosion rate on the metallic surface is higher at some localized geographical area of the globe. Despite the visible successes in recent coating technology in curbing environmental conditions, it is proposed that the recent increase of atmospheric bioaerosols has a significant role in the dissolution of corrosion-resistant coating over a metallic surface. In this review, the science of atmospheric corrosion on metallic materials was reviewed in the light of the chemical and physical composition of atmospheric bioaerosols and aerosols. It was observed that aside from general conditions (i.e., alloying element level, surface roughness, surface treatment, and microclimate), the bioaerosols content is essential for future research in corrosion. It is recommended that further experimental research be carried out to corroborate the science of atmospheric bioaerosols to different forms of corrosion.

Galvanised steel atmospheric corrosion is a complex multifactorial phenomenon that globally affects many structures, equipment, and sectors. Moreover, the International Organization of Standardization (ISO) standards require specific pollutant depositions values for any atmosphere classification or corrosion loss prediction result. The aim of this research is to develop predictive models to estimate corrosion loss based on easily worldwide available parameters. Experimental data from internationally validated studies were used for the data mining process, basing their characterisation on seven globally accessible qualitative and quantitative variables. Self-Organising Maps including both supervised and unsupervised layers were used to predict first-year corrosion loss, its corrosivity categories, and an uncertainty range. Additionally, a formula optimised with Newton’s method has been proposed for extrapolating these results to long-term results. The predictions obtained were compared with real values using Euclidean distances to know its similarity degree, offering high prediction performance. Specifically, evaluation results showed an average saving of up to 16% in coatings using these predictions. Therefore, using the proposed models reduces the uncertainty of the final structures state by predicting their material loss, avoiding initial over-dimensioning of structures, and meeting the principles of efficiency and sustainability, thus reducing costs.

“…The uncalcined Rust NPs show peaks at about 1033cm − 1 , which might be due to the lepidocrocite (ferric mineral) (Veneranda et al 2018).The peaks at about 903 and 799 cm − 1 might be due to the goethite (hydrated iron oxide) (S and A 1993). The absorption peak in the absorption band of uncalcined Rust at 1630 cm − 1 is the characteristic peak of -OH, indicating a large amount of crystal water in the corrosion products (Wang et al 2020). This peak almost disappears in the calcined Rust due to high-temperature calcination.…”

At present, wastes management and energy generation are the foremost concerns due to their direct relationship with the biological species and environment. Herein we report utilization of iron rust (inorganic pollutant) as photocatalyst for photodegradation of methylene blue (MB) dye (organic pollutant) under visible light (economic) and water oxidation (energy generation). Iron rust was collected from metallic pipes and calcined in the furnace at 700 °C for 3 h in order to remove moisture/volatile content. The uncalcined and calcined Rust are characterized through scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), and Fourier transform infrared (FTIR) analysis, X-Ray Diffraction (XRD) and Thermogravematric analysis (TGA). The morphological study illustrated that the shape of uncalcinedand calcined iron rust is spongy, porous, and agglomerated. The XRD and DLS particle size is in a few hundred-nanometer range.The photodegradation (PD) investigation shows that calcined Rust is a potent photocatalyst for the PD of modeled MB and degraded about 94% in a very short time of 11 min. The photoelectrochemical (PEC) measurements revealed that calcined Rust is more active than uncalcined Rust under simulated 1-SUN illumination with respective photocurrent densities of ~0.40 and ~0.32 mA/cm2. These results demonstrate that cheaper and abundantly available Rust can be a useful candidate for environmental and energy applications.
