“…the analyzed area must be chosen in order to be representative of the different topological features but limiting the number of spectrum to be collected and processed to built smart images (Colomban, 2003;Havel et al, 2004;Havel & Colomban, 2006;Gouadec et al, 2010). The image resolution will thus depend on the optical parts (objective and spectrometer), the laser beam quality (alignment, fundamental mode), the sample (parasite refractions at interfaces, roughness), Raman signature contrast, light absorption and penetration in the sample as well as the stage motion step, usually up to 0.1 µm.… The mapping has been used to understand the long term atmospheric and in soil corrosion taking advantage of the big thickness and large grain size of corrosion films (tenths of microns) present in heritage buildings (cathedrals, churches,…) and archaeological artefacts (Neff et al, 2005;ibidem, 2006;Monnier et al, 2010). Archaeological and Cultural Heritage artefacts are however considered as good analogues for the understanding and prediction of iron alloys corrosion behaviour in soil and in atmosphere, and hence to determinethe lifetime of over-containers used to protect the vitrified nuclear waste.…”

“…According to many authors (Turgoose, 1982;Selwyn et al, 1999;Dillmann et al, 2004;Neff et al, 2005) akaganeite forms mainly in the inner part of the corrosion layer near the metal-oxide interface of corroded steel. But akaganeite has also been identified in the outer part of thick rust layers formed on carbon steels exposed to air in a coastal region (Asami and Kikuchi, 2003).…”

Basic research on marine atmospheric corrosion of carbon steels is a relatively young scientific field and there continue to be great gaps in this area of knowledge. The presence of akaganeite in the corrosion products that form on steel when it is exposed to marine atmospheres leads to a notable increase in the corrosion rate. This work addresses the following issues: (a) environmental conditions necessary for akaganeite formation; (b) characterisation of akaganeite in the corrosion products formed; (c) corrosion mechanisms of carbon steel in marine atmospheres; (d) exfoliation of rust layers formed in highly aggressive marine atmospheres; (e) long-term corrosion rate prediction; and (f) behaviour of weathering steels. Field research has been carried out at Cabo Vilano wind farm (Camariñas, Galicia) in a wide range of atmospheric salinities and laboratory work involving the use of conventional atmospheric corrosion techniques and near-surface and bulk sensitive analytical techniques: scanning electron microscopy (SEM)/energy dispersive spectrometry (EDS), X-ray diffraction (XRD), Mössbauer spectroscopy and SEM/μRaman spectroscopy. RESUMEN:Corrosión atmosférica marina de aceros al carbono. La investigación fundamental en corrosión atmosférica marina de aceros al carbono es un campo científico relativamente joven que presenta grandes lagunas de conocimiento. La formación de akaganeíta en los productos de corrosión que se forman sobre el acero cuando se expone a atmósferas marinas conduce a un incremento notable de la velocidad de corrosión. En el trabajo se abordan las siguientes cuestiones: (a) condiciones ambientales necesarias para la formación de akaganeíta, (b) caracterización de la akaganeíta en los productos de corrosión formados, (c) mecanismos de corrosión del acero al carbono en atmósferas marinas, (d) exfoliación de las capas de herrumbre formadas en atmósferas marinas muy agresivas, (e) predicción de la velocidad de corrosión a largo plazo, y (f) comportamiento de aceros patinables. La investigación se ha llevado a cabo en campo, en el Parque Eólico de Cabo Vilano (Camariñas, Galicia) en un amplio rango de salinidades atmosféricas, y a nivel de laboratorio acudiendo a técnicas convencionales de corrosión atmosférica y diversas técnicas analíticas de caracterización de superficies: microscopía electrónica de barrido (MEB)/ espectrometría de dispersión de energía (EDE), difracción de rayos-X (DRX), espectroscopía Mössbauer y MEB/espectroscopía μRaman.

“…In previous studies, glass diseases such as crizzling crying glass, weathering and glass crystallization are documented [8][9][10]. Also, the corrosion of metal objects was frequently described in the literature [11,12]. Corrosion of stained glass and enamel has been described, largely focusing on the corrosion of individual components [13].…”

'Glass sensors' of the eighteenth century Backer glass and the sixteenth century enamel from Limoges have been chosen for a series of experiments. Combinations of these materials with different base materials such as copper and bronze has been investigated. To create surface changes on the 'glass sensor', a corrosion process was induced in a controlled environment. A variety of corrosive agents such as hydrochloric acid, sulfuric acid, water and formaldehyde were used. The sample immersed in the corrosive solution was exposed alternately to light and high temperature for a total of 38 weeks. During this period, macroscopic and microscopic observations were made and series of tests such as SEM/EDS and Raman spectroscopy were performed on the surface of the samples. ICP-MS methods were used to determine the change in the chemical composition of the solutions where the samples had corroded. The primary aim of this study was to identify the impact of a number of external corrosive variables such as temperature, humidity and local environment to identify the most damaging environments for glass-metal objects. The obtained results showed the chemical and physical phenomena acting on the surface of the glass, metal or in the place of their joints. Information obtained on this study was used to explain the influence of the environment on the surface of glass-metal materials. Results can be used in the design of conservation work as well as for sustainable conservation.
