Download The Development of an Accelerated Tarnish Test for Sterling Silver Book in PDF, Epub and Kindle
The slow discolouration and unattractive appearance of the tarnish that forms when silver is exposed to an atmosphere is an unfortunate consequence in silver jewellery. In order to evaluate the resistance of silver to tarnish, it is important to develop a test. This paper describes the development of an accelerated test to determine the tarnish performance of Sterling Silver.

Download Corrosion and conservation of cultural heritage metallic artefacts Book in PDF, Epub and Kindle
The use of silver in ancient civilisations of Mesopotamia, Egypt, Ionia, Greece, Rome and China is presented. Principles of silver corrosion in different environments containing humidity, oxygen, carbonates, sulphur, chlorides, peroxides, ozone and UV, and the morphology of the corrosion layers are described. Cleaning, anti-tarnishing and protection methods are explained. Inhibitor hexadecanethiol (HDT) and a composite coating of Paraloid B-72 containing 2% nano-alumina pigment are tested on silver specimens with tarnished and corroded surfaces and found to be protective when exposed in sulphides and chloride environments in the laboratory, satisfying aesthetic and reversibility criteria.

Download Corrosion and Conservation of Cultural Heritage Metallic Artefacts Book in PDF, Epub and Kindle
The conservation of metallic archaeological and historic artefacts is a major challenge whether they are ancient bronzes or relics of our more recent industrial past. Based on the work of Working Party 21 Corrosion of Archaeological and Historical Artefacts within the European Federation of Corrosion (EFC), this important book summarises key recent research on analytical techniques, understanding corrosion processes and preventing the corrosion of cultural heritage metallic artefacts.After an introductory part on some of the key issues in this area, part two reviews the range of analytical techniques for measuring and analysing corrosion processes, including time resolved spectroelectrochemistry, voltammetry and laser induced breakdown spectroscopy. Part three reviews different types of corrosion processes for a range of artefacts, whilst part four discusses on-site monitoring techniques. The final part of the book summaries a range of conservation techniques and strategies to conserve cultural heritage metallic artefacts.Corrosion and conservation of cultural heritage metallic artefacts is an important reference for all those involved in archaeology and conservation, including governments, museums as well as those undertaking research in archaeology and corrosion science. Summarises key research on analytical techniques for measuring and analysing corrosion processes Provides detailed understanding of corrosion processes and corrosion prevention Discusses on-site monitoring techniques

Download Further Developments of Surface Coatings to Improve the Tarnish Resistance of Silver Alloys Book in PDF, Epub and Kindle
Several methods have been developed to reduce the formation of tarnish on silver; these include alloying, surface treatments and coatings. The authors evaluated a range of commercially available surface treatments and coatings in earlier research, using the Tucillo-Nielson accelerated tarnish test. Four surface treatments/coatings increases the time to noticeable tarnish by more than ten fold. The results of this research were reported at a previous International Corrosion Congress (ICC), at other corrosion conferences and in corrosion journals.

Download Tarnish Resisting Silver Alloys (Classic Reprint) Book in PDF, Epub and Kindle
Excerpt from Tarnish Resisting Silver Alloys The preliminary survey by the Bureau of Mines had indicated that one of the promising possibilities of any attempts to increase the use of silver wouldbe the development of a silver alloy which should be nontarnishing, or at least less tarnishing than the usual sterling silver (copper-silver).

Download Metallography and Microstructure in Ancient and Historic Metals Book in PDF, Epub and Kindle
David A. Scott provides a detailed introduction to the structure and morphology of ancient and historic metallic materials. Much of the scientific research on this important topic has been inaccessible, scattered throughout the international literature, or unpublished; this volume, although not exhaustive in its coverage, fills an important need by assembling much of this information in a single source. Jointly published by the GCI and the J. Paul Getty Museum, the book deals with many practical matters relating to the mounting, preparation, etching, polishing, and microscopy of metallic samples and includes an account of the way in which phase diagrams can be used to assist in structural interpretation. The text is supplemented by an extensive number of microstructural studies carried out in the laboratory on ancient and historic metals. The student beginning the study of metallic materials and the conservation scientist who wishes to carry out structural studies of metallic objects of art will find this publication quite useful.

Download Atmospheric Corrosion Book in PDF, Epub and Kindle
ATMOSPHERIC CORROSION Presents a comprehensive look at atmospheric corrosion, combining expertise in corrosion science and atmospheric chemistry Atmospheric corrosion has been a subject of engineering study, largely empirical, for nearly a century. Scientists came to the field rather later on and had considerable difficulty bringing their arsenal of tools to bear on the problem. Atmospheric corrosion was traditionally studied by specialists in corrosion having little knowledge of atmospheric chemistry, history, or prospects. Atmospheric Corrosion provides a combined approach bringing together experimental corrosion and atmospheric chemistry. The second edition expands on this approach by including environmental aspects of corrosion, atmospheric corrosion modeling, and international corrosion exposure programs. The combination of specialties provides a more comprehensive coverage of the topic. These scientific insights into the corrosion process and its amelioration are the focus of this book. Key topics include the following: Basic principles of atmospheric corrosion chemistry Corrosion mechanisms in controlled and uncontrolled environments Degradation of materials in architectural, transport, and structural applications; electronic devices; and cultural artifacts Protection of existing materials and choosing new ones that resist corrosion Prediction of how and where atmospheric corrosion may evolve in the future Complete with appendices discussing experimental techniques, computer models, and the degradation of specific metals, Atmospheric Corrosion, Second Edition continues to be an invaluable resource for corrosion scientists, corrosion engineers, conservators, environmental scientists, and anyone interested in the theory and application of this evolving field. The book concerns primarily the atmospheric corrosion of metals and is written at a level suitable for advanced undergraduates or beginning graduate students in any of the physical or engineering sciences.
