Long-term corrosion behaviour of low-carbon steel in anoxic environment: Characterisation of archaeological artefacts

Oxidation of chukanovite (Fe 2 (OH) 2 CO 3 ): Influence of the concentration ratios of reactants

“…This compound has a structure very similar to that of chukanovite [13]. These results are also in agreement with previous analysis of corrosion product layers of ferrous archaeological artefacts that showed chukanovite often associated with goethite ␣-FeOOH while no GR compound was found [2,3].…”

“…However, the mostly reported Fe(II) hydroxysalt is the Fe(II)-hydroxycarbonate chukanovite (Fe 2 (OH) 2 CO 3 ). It has been commonly found as a main component of the corrosion product layers formed on iron archaeological artefacts excavated form anoxic soils [2][3][4]. It was also observed on carbon steel buried in clay at 80-90 • C [5,6], i.e.…”

Raman study of a deuterated iron hydroxycarbonate to assess long‐term corrosion mechanisms in anoxic soils

“…[13] In this site, chemical parameters of the soil were measured on-site to ensure that the sampling zone was anoxic. [13] This site is an old iron-making site of the 16th century. [26] Nails were excavated between July 2006 and July 2008 at about 1 m Table 1.…”

Submerged Paleolandscapes: Site GNL Quintero 1 (GNLQ1) and the First Evidences from the Pacific Coast of South America

“…Palaeolama sp. humerus were found, suggesting an anoxic depositional environment and the action of sulphur-reducing bacteria (Borrego et al 2003;Brown et al 2010;Saheb et al 2008). This is coincident with the oxidation staining found in all the assemblage resulting from the interaction of the bones with an interface of gravel clay sediment and water, which is characteristic of the depositional environment of the GNLQ1 site (Dunbar et al 1989;Noakes et al 2009).…”
