Corrosion is a dynamics process. Molecular dynamics (MD) simulations facilitate the study of the dynamic behaviour of atoms and molecules on larger spatial scales over time, providing a detailed microscopic view of the corrosion process. The trajectory of an MD simulation, which is a comprehensive record of the time-evolution of the positions, velocities, and sometimes other properties of all particles (atoms, molecules, or ions) in the simulated system, provides insights into the time evolution behaviour of the system. Moreover, MD simulations can model the influence of various environmental factors on corrosion, such as temperature, pressure, and the presence of different chemical species. Ultimately, together with DFT calculations, MD simulations can provide insights into corrosion protective mechanisms and guide the design of more effective inhibitors.
