“…The identical participation of Clis also very likely present in the metal dissolution process in DESs [28,56]. Furthermore, by identifying FeOCl in the corrosion products at steel immersed in ethaline and reline, Kityk et al [56] concluded that the chloride ion present in large concentrations even changes the mechanism and accelerates steel corrosion in DES, in comparison to water solution. Particularly, Clions enable the formation of FeOCl, an intermediate compound that facilitates the formation of γ-FeOOH [56].…”

Deep eutectic solvents (DESs) are a class of mixtures with melting points notably lower than those of their raw constituent components. These liquids have found a tremendously wide spectrum of applications in the last two decades of their research, so their contact and interaction with technical metals and alloys are inevitable. Therefore, the corrosivity of DESs towards metals is an extremely important topic. This review summarizes research efforts collected in the last two decades related to the corrosion rate of various metals in different DESs. Since the DESs are mainly composed of organic raw compounds, and by their physicochemical properties they may be regarded as a separate class of ionic liquids, the literature data about DESs corrosivity has been compared to the data related to the corrosivity of various organic solvents and ionic liquids as well. All the results gained until now show significantly low corrosivity of DESs. This observation is discussed in relation to the chemical composition of DESs. The absence of the oxidizing agents, the inhibitory action of organic ions and molecules, high viscosity and low electrical conductivity have been recognized as the main factors contributing to the low metal corrosion rate in DESs.

“…O x (OH) y transforms through further slow oxidation into green rust (precipitate of Fe 2+ and Fe 3+ ) or through rapid oxidation into magnetite Fe 3 O 4 [26]. The green rust stage is followed by the formation of lepidocrocite γ-FeO(OH), which then transforms into a final oxide.…”

Microstructure and long-term corrosion of archaeological iron alloy artefacts

et al. 2020

The smithing skills of craftsmen in the western Mediterranean during the early Iron Age can be determined by studying the microstructure of oxidised iron items. While some ghost structures have already been identified in dense corrosion products, their formation has not always been explained. Four objects from southern France were analysed using optical microscopy, X-ray diffraction, micro-Raman spectroscopy and field-emission scanning electron microscopy coupled with energy dispersive spectroscopy and electron backscatter diffraction. The role of microstructure, grain boundaries, cracks, species diffusion through oxides in soil corrosion and the initial microstructure are discussed. An additional parallel degradation mechanism (graphitisation) was experimentally revealed.
