Corrosion is a complex electrochemical process that involves the interaction of metal (iron) surfaces with their environment, leading to formation of various corrosion products such as metal oxides and hydroxides. The versatile interactions between the metal and its environment make the process of corrosion inherently complex. For instance, reinforcing steel structures in concrete are usually protected by a passive layer, whose stability highly depends on environmental factors such as pH and aggressive ion concentrations. A decrease in pH or an increase in aggressive ions like chloride can initiate corrosion by degrading the passive layer. Historically, corrosion-related research has been based on experimental techniques.
