Understanding long term corrosion processes is critical in many areas, including archaeology and conservation. This important book reviews key themes such as the processes underlying corrosion over long periods, how corrosion rates can be measured and materials conserved. After an overview of the study and conservation of metal archaeological artefacts, a group of chapters reviews long term corrosion in metals such as steel, iron and bronze. Other chapters review the impact of environmental factors on corrosion rates. The book also considers instrumental techniques for measuring corrosion such as electrochemistry and scanning electron microscopy, as well as ways of modelling corrosion processes. There is also coverage of the effectiveness of corrosion inhibitors. With its distinguished editors and contributors, Corrosion of metallic heritage artefacts improves our understanding of long term corrosion and its effects. It provides a valuable reference for those involved in archaeology and conservation, as well as those dealing with the long term storage of nuclear and other waste.

Oxygen is a key factor in corrosion and decay of artefacts from our cultural heritage. The measurement of oxygen concentrations and quantification of oxygen consumption is therefore extremely useful in both corrosion and conservation science. This chapter focuses on two aspects of oxygen monitoring: first, measurement of oxygen consumption of

Metallographic investigations may be an essential component in the search for authenticity and fabrication technology. Assessing how an artefact is made may involve metallographic examination, usually entailing the removal of a small sample from the object concerned. Examples of the use of metallography are discussed with reference to copper alloys,

Relationships between conservation and corrosion scientists are assessed and similarities, differences and synergies identified. Corrosion control as a preservation option for heritage metals is advocated as being cost-effective and pragmatic. This will require generation of data to develop predictive conservation and estimation of object lifespan as a function of their

This chapter introduces the techniques used when investigating corrosion layers formed on cultural heritage artefacts. Various multiscale analysis methods, from macroscopic to nanoscopic scales, are presented. Information on the morphology, the elementary composition and the crystalline structure that each method allows for determining the constituents of the corrosion layers is

In the present chapter laser-induced breakdown spectroscopy (LIBS) is introduced as a powerful spectrochemical analytical technique that can be exploited to characterize corroded artifacts. Scientific and technological aspects of LIBS are briefly presented. LIBS does not need sample preparation, it is nondestructive and it can be used for in-situ measurements.

This chapter discusses the evaluation of metal conservation treatments using a specialized electrochemical cell. The cell can be deployed in a synchrotron beam line to make in-situ, time-lapse measurements on heritage metal alloys undergoing processes based on electrochemical treatments/measurements. We focus on two specific projects: (1) the evaluation of currently

Electrochemical impedance spectroscopy (EIS) is a powerful tool in developing the most appropriate methodology for ensuring long-lasting artefact preservation. EIS consists in the measurement of amplitude and phase of the surface impedance of coated metallic objects at different frequencies in order to highlight either the protective effectiveness of a coating

This chapter describes the recent advances in corrosion protection afforded by the use of ultra-thin organic films such as polymer films and self-assembled monolayers. Emphasis is given to the metal surface modification by self-assembled monolayers of carboxylic acids due to their properties and ability to protect metallic artefacts.

This chapter discusses the application of the voltammetry of microparticles, a solid-state electrochemical technique, to the field of corrosion of archaeological metal. Identification of metals and alloys, identification, mapping and layer-by-layer analysis of corrosion products on metal surfaces using this technique are described. Applications include quantification of components of alloys

This chapter gives general information on the production of sol-gel coatings with alkoxysilanes. Some examples of their application on outdoor bronze artefacts are reported. The protective effects of 3-mercapto-trimethoxysilyl-propane (Prop-SH) hydroalcoholic solution on polished and patinated bronzes were studied. Electrochemical tests, performed in acidic artificial rain (AAR, pH 3.1) and in 5%
