Special Issue Information

Dear Colleagues,

In recent decades, the development of mathematical models representing chemical and physical phenomena, as well as the application of modern computing simulations to analyze them, have experienced huge advancement. These methods have found applications in predicting atmospheric corrosion (i.e., via machine learning), characterizing corrosion inhibition mechanisms and their relationship with the molecular characterize structure and the adsorption processes, pit corrosion nucleation and growth, erosion-corrosion, crevice corrosion, and stress-corrosion cracking processes in industry. The development of new algorithms is also employed to improve the power of the software employed for the analysis of EIS data. Altogether, these examples reflect the important role that computational simulation plays in the field of corrosion. Moreover, climate change and global warming may affect the atmospheric corrosion processes, mostly by their extreme events.

This Special Issue focuses on Computational Simulation and Experimental Investigations on Corrosion of Materials as it relates to atmospheric influence, exploring the greatest advances in the field of corrosion prevision and surface modification by corrosion modeling. Topics include, but are not limited to, materials corrosion analysis by computational simulation, density functional theory (DFT), Monte Carlo (MC), molecular dynamics (MD), and RF-based machine learning.

Mathematical modelling and software simulation nowadays are very effective tools for both understanding and predicting corrosion processes and the protection of metallic components. COMSOL Multiphysics 5.6 software provides validated mathematical models that can be used, for a given geometry, as a tool to predict and prevent corrosion of components. The corrosion of zinc-coated steel sheets has been studied in this work by comparing results of the simulations with laboratory tests carried out in a salt spray. Results of both the mathematical modelling and empirical tests give the possibility to estimate the stability of the protective zinc layer over time. The examination of the discrepancies between two analytical methods for the investigation of corrosion phenomena leads to possible modifications in the model in order to reach as much as possible coherence with experimental data. As a final result, a computational model of corrosion phenomena in an automotive component has been reached, allowing in the future to partially substitute laboratory tests, usually being highly time consuming and expensive.

Polyvinyl butyral (PVB) is a thermoplastic resin commonly used as an interlayer material in laminated glass. Combined with textile fibres from worn tyres, PVB can produce a composite material with unique properties. One such property is absorption. Absorption in textile fibre composite materials refers to the ability of the material to absorb or retain moisture or other fluids. The presence of moisture or liquids can affect the properties of composite materials, such as their strength, stiffness, and dimensional stability. As a result of the physical and chemical action of the environment, corrosion of plastics occurs and manifests itself in changes in appearance, surface quality, weight, dimensions, and also in changes in other properties. This paper investigates four composite materials with different fabrics content. The aim of this paper is to propose a generalized mathematical model for absorption values so that, with different ratios of textile fibre in the material, its quality indicators are at a sufficient level. Our study will proceed from the assumption that by changing the values of the individual coefficients of the selected model based on their analysis, we will achieve the required qualitative indicators.
