“…Such observations validated an important correlation between oxide stability and faradaic efficiency of noble metals and alloys, broadly applicable to electrocatalysis applications. Dworschak et al [ 113 ] reported using ASEC analysis that hydrophobic thiol‐based self‐assembled monolayers on Au surface suppress the dissolution during oxygen evolution to some extent (Figure 11c).…”

A fundamental understanding of corrosion mechanisms is the key to developing suitable corrosion protection approaches, and for the prediction of service life of metallic structures. However, conventional corrosion testing methods such as mass loss and electrochemical testing do not guarantee estimation of "true" corrosion rate and often mask the underlying mechanisms, due to either low sensitivity or a lack of element-resolved information. Relatively recent work in corrosion science has led to the development of a new class of corrosion testing approaches, namely atomic spectroelectrochemistry; whereby direct insight of dissolution and corrosion mechanisms can be obtained during electrochemical testing. Atomic spectroelectrochemistry provides real-time and element resolved dissolution rate of material via coupling electrochemical flow cell with inductively coupled plasma -atomic spectroscopy. This concise review discusses the basic working principle of atomic spectroelectrochemistry and its recent applications in corrosion science to understand the true underlying corrosion mechanisms of a range of metallic materials.

“…The attack over metallic materials by fungus is explained by the fact that from fungus metabolism a lot of organic acids, like tartric, citric and oxalic acid, solubilize the metals [12][13][14][15][16][17][18][19]. The corrosive action of fungus over metal material is accentuated in warm and humid areas where damages are very important [20][21][22][23][24]. The species of fungus which attack metallic materials and plastic materials are: Trichoderma, Neurospora, Fusarium sp., Aspergillus sp., Penicillium sp., Chaetomium and Sterigmatocystis [21][22][23][24].…”

“…There is organic compound that exists in the structure of vegetable extracts which can be divided into hydrophobic and hydrophilic compounds [18][19][20][21][22]. Hydrophobic compounds provide protection from the metallic surface while the hydrophilic compounds prevent corrosion by being adsorbed on the surface and constructing a biofilm [28,29].…”

Corrosion is a process that involves the action of different agents on material surfaces. Corrosive agents in corrosion field can be ambient, saline and microbiological mediums. These agents can influence the mechanical properties of metallic material like steel. The aim of this research is to present the mechanic properties of sheet steel submitted at the action of corrosive agents. The metallic samples were analyzed in order to determinate the resistance at corrosion by stress-strain curves, deformation limit curves and (Atomic Force microscopy) AFM images. Relative results are obtained in the case of saline medium corrosion, meaning that the saline medium corrosion influences the metallic sample, in proportion to the degree of salinity. Also, the AFM images and topographies of metallic surface confirm this conclusion.
