Book Description
"This special issue of Corrosion Engineering Science and Technology is dedicated to the study of corrosion of objects from historical sites. The issue contains contributions from the 2009 EUROCORR session on Corrosion of Archaeological and Heritage Artefacts organised by the European Federation of Corrosion's working party and commissioned articles on other key issues. The objective is to give the reader a broad understanding of corrosion of ancient materials, for the most part metal but also glass. Articles shed light on a range of analytical approaches related to the study of the complex systems that make up historical artifacts. In order to arrive at an understanding of the nanometric organisation of rust layers and interphases, such studies must be approached on a macroscopic scale. Techniques used include; macrophotography, synchrotron radiation and transmission electron microscopy (TEM) that ensure results that are both exhaustive and representative of particular observations. This issue demonstrates the wealth of approaches possible in the study of the corrosion of ancient materials."

Book Description
This chapter deals with the description of suitable and innovative solutions devoted to preserve metallic artefacts in their original contexts, underwater cultural heritage sites of archaeological and historical interest, as well as with the analysis of the degradation processes of ferrous and non-ferrous artefacts induced by contact with an aggressive environment such as sea water. The chapter also provides an overview of the most common conservation strategies applied to recovered artefacts.

Book Description
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. Examples of LIBS applications that can help archaeologists in conservation and restoration of metallic artifacts are given. We demonstrated the use of LIBS in analysis of corroded metal threads, depth profiling of copper-based decorative artefact, analysis of corroded Punic coins, and LIBS and XRF analysis of Roman silver denarii.

Book Description
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 cultural heritage artefacts to evaluate their corrosion rate and the efficiency of conservation treatments, and second, measurement of oxygen concentration in the burial environment to evaluate the preservation conditions and understand the formation of different corrosion products in situ. The chapter includes a short description of equipment for oxygen measurement, and gives some examples of its use for monitoring purposes.

Book Description
The basic principles of corrosion and electrochemistry are briefly summarised to indicate the capabilities of electrochemical techniques in diagnostic and conservation of heritage metals. The basic elements of each electrochemical measurement – cell, electrolyte, instrumentation – are schematically illustrated in the specific application to cultural heritage. The different measurement techniques are reviewed, divided into three groups: (1) potential measurements; (2) DC techniques; (3) AC techniques. The aims and fields of application are discussed, reporting several examples of specific applications in the field of cultural heritage.

Book Description
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 or the stability of a corrosion product layer grown onto the metallic surface. Two in-situ EIS measuring campaigns are described together with the description of the portable instrument and the measuring probes specifically designed and developed for cultural heritage applications.

Book Description
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 and corrosion layers, and evaluation of metal conservation and the kinetics of long-term corrosion processes. Specific applications in archaeometry, conservation and restoration include authentication and dating.

Book Description
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, high-tin bronzes, Chinese bronze mirrors, copper plaques, iron and steels, and plated or coated metals, such as depletion gilded surfaces or those covered with gold foil or other metals. The different types of features which metallography can reveal concerning ancient metallic structures are briefly discussed with several colour photomicrographs which illustrate the features described in this chapter. The importance of metallography as one component of the scientific tools to aid in the determination of authenticity of ancient metallic artefacts is stressed, and an example given of old electrotypes from the Victoria and Albert Museum. Important literature references are provided to direct the reader to more detailed studies on the subject.

Book Description
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 examined, as well as their limits in terms of set-up, spatial and detection resolution. This chapter discusses the characteristics of the scientific tools that can be used to understand corrosion phenomena, by taking into account the major parameters responsible for alteration mechanisms.
