Corrosion of Metallic Heritage Artefacts Excerpt :

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.

Corrosion and conservation of cultural heritage metallic artefacts Excerpt :

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.

This chapter reviews the applicability and specific uses of corrosion inhibitors in metal conservation practice. Corrosion inhibitors are one of the different methods used by conservation-restoration professionals to preserve metallic cultural heritage. In the first part, specific requirements and needs for corrosion inhibitors in conservation treatments are reviewed, as well as the different methods for the assessment of their efficiency. The second part of the chapter reviews the different inhibitors used by type of metals: copper and its alloys, iron and its alloys, and other metals (including silver, lead and zinc), from traditional ones to state-of-the-art treatments.

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.

Corrosion and conservation of cultural heritage metallic artefacts Excerpt :

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 intrinsic and extrinsic variables. Methods for quantitative determination of corrosion rates of chloride infested heritage iron and techniques for scaling to heritage value are discussed. The iron hull of the ss Great Britain and an AHRC/EPSRC Heritage Science Research Programme at Cardiff University are used to illustrate the rationale behind using corrosion control in heritage.

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.

This chapter deals with an overview of the application of plasma technologies, an innovative environmentally friendly class of processes for the surface modification of materials, for cleaning and protection of metallic artefacts. Examples of plasma enhanced chemical vapour deposition (PECVD) of organosilicon precursors are described and appear particularly promising for the corrosion protection of the different metallic substrates such as iron-based alloys, copper and silver-based alloys of archaeological and historical-artistic interest.

This chapter attempts to address monitoring problems from a wider point of view than is usual in the cultural heritage field. It discusses the issues connected to variations of space and time in the measured quantities. Some differently structured systems which can be employed in designing a monitoring infrastructure are discussed and a case study is reported to illustrate the practical application of general guidelines.

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.

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.

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 used stabilization processes for cupreous objects recovered from marine environments, and (2) the development and testing of a coating to protect lead objects which is stable, reversible (i.e. easy to apply and to remove), protective against corrosion and aesthetically justified.

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% NaCl solution for 168h, were checked in 45d AAR Salt Cabinet and in 30d ASTM B117 Test on bronze statues. The treatment with Prop-SH showed high efficiency towards the corrosion both in AAR and in 5% NaCl.
