“…Dillmann et al: "Recent advances in the understanding of atmospheric corrosion mechanisms"In the last decade great advances has been made in the understanding of atmospheric corrosion mechanisms. Many of these advances have been due to Legrand et al[65,[109][110][111] and Dillmann et al[60,71,[112][113][114][115]. The basic research carried out on this field is related with a greater knowledge of the electrochemical reactivity of the ferric phases that constitute atmospheric rust, the coupling or decoupling of anodic and cathodic reactions, and knowing at which interface (metal/corrosion product layer (CPL) or CPL/environment) the different phases are formed.…”

The design of the first weathering steels was purely empirical and focused on a small number of conventional alloying elements such as manganese, silicon, chromium, nickel, copper and phosphorus, mainly. The environmental conditions that promote the formation of protective rust layers: existence of wet/dry cycling, absence of very long wetness times, atmospheres without a marine component, etc., were identified by trial and error. This paper makes a bibliographic review of the abundant literature that has been published on the atmospheric corrosion of weathering steels, setting out in chronological order the advances made in the scientific knowledge of important matters such as: atmospheric corrosion mechanisms of weathering steel, formation of protective rust layers, and the role played by alloying elements. The work ends with an overview of the scientific design of new weathering steels, placing special emphasis on the new compositions developed for application in marine atmospheres.

“…The wet (aqueous) corrosion is studied using electrochemical methods while the dry corrosion is analyzed using physical measurements made periodically on samples exposed during long periods of time [3][4][5][6][7]. Some works concerning the kinetic inquiry into the initial atmospheric corrosion is however available in the literature [8].…”

ABSTRACT. The corrosion behavior of three constructional steels used in Senegal, S235, S275 and S355, was studied in simulated atmospheric conditions in an exposure chamber above distilled water and above 3% NaCl solution representing marine atmosphere by comparing the ratio of rusted to unrusted area. Electrochemical test methods (potentiodynamic tests and electrochemical impedance spectroscopy) were employed to study the steels fully immersed in acidic, near neutral and basic conditions in 0.5 M HCl, NaCl, and NaOH solutions, respectively. Results indicate that S355 and S235 steels have comparable corrosion resistance, which are much lower than that of S275.

“…The reactivity and the electronic properties of the phases in the corrosion layer can strongly infl uence the processes and the corrosion rate (Antony et al, 2007;Monnier et al, 2007;. The location of the reaction sites inside the corrosion layer and its reactivity are studied using reaction marking (Vega et al, 2005;Chitty et al, 2008;Burger et al, 2011;Monnier et al, 2011) and electrochemical tests (Pons 2002;Monnier et al, 2007). The modelling of the in situ conditions on the one hand and the establishment of the corrosion rates and mechanisms on the other hand allow diagnosing the alteration state of the archaeological remains in order to improve the conservation strategy.…”

In the context of the cultural heritage, a methodology based on fi eld and laboratory approaches is developed for studying the long-term corrosion of iron. Moreover it has been adapted to the study of archaeological artefacts buried in anoxic soils in the specifi c case of in situ preservation. The environmental parameters are determined on the archaeological sites and artefacts are collected and characterized using complementary multi-scale techniques. Moreover, laboratory experiments are performed to locate the reaction sites inside the corrosion layer and to identify its electronic properties. The results allow estimation of a low corrosion rate for iron buried in an anoxic soil (under 2 µm/year) and the proposal of a mechanism based on a decoupling of the anodic and the cathodic sites. Then a diagnosis of the alteration state of the samples is established.keywords in situ preservation, anoxic water-saturated environment, iron corrosion fi gure 1 General approach used for the study of ferrous archaeological artefacts (from Neff et al., 2010).
