Corrosion and conservation of cultural heritage metallic artefacts by D. Neff,S. Reguer,P. Dillmann Pdf

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 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.

Corrosion and conservation of cultural heritage metallic artefacts by D.A. Scott Pdf

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 discusses the importance of using standards in conservation methodology and practice for cultural heritage (CH) metals. The past general trend in the field is the use of metal industry standards. The chapter surveys the relevant scientific publications, and concludes that conservation researchers use a variety of these standards adopted by different organisations. As a result, it can be difficult to compare scientific data for CH metal studies carried out by different laboratories. The chapter discusses the necessity to draft new standards for metals specific for CH by examining how three independent researchers had different findings when testing the same coating. The role of CEN/TC 346 ‘Conservation of Cultural Heritage’ is also discussed.

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 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.

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 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.
