Code: EP26 Contents of this page:Description DescriptionThe purpose of this book is to describe the methods which can be used to measure the thickness of electrodeposited and electroless (autocatalytic) coatings on both metallic and non-metallic substrates, conversion and hot-dipped coatings on metallic substrates, vitreous enamel coatings on metals, anodic coatings on aluminium and other metals and chemical replacement coatings on metallic substrates. Many of the methods, especially some of those based on non-destructive techniques, are equally applicable to organic coatings deposited on metallic substrates. The book attempts to give sufficient details of the test methods for them to be carried out without reference to any of the literature, apart from the instruction supplied by the instrument manufacturers for their particular instruments. The first part of the book deals with Destructive Testing Methods such as Microscopical examination of the cross-sections, Coulometric, Jet test and Strip and Weigh methods. The second part describes Non-destructive methods: Magnetic, Beta backscatter, X-Ray Spectrometry, Eddy current and Breakdown voltage methods. Profilometric and Optical methods, which may be described as almost non-destructive techniques, are included in the second part of the book. A brief list of some well-known instrument manufacturers has been included for guidance purposes. The book concludes with a list of current international (ISO), British (BS) and US (ASTM) Standards to assist both metal finishers and the users of their products. Some Worldwide Reviews"The subject matter is well presented with a practical, down to earth approach. It seems clear that the book has been written with the needs of people in industry firmly in mind, and to such people I would have no hesitation in recommending it." Hybrid Circuits (UK) About the EditorAfter obtaining his professional membership of the Institution of Metallurgists (now Institute of Materials), Dr Ray attended Sir John Cass School of Science and Technology, City of London Polytechnic, gaining an MSc degree in corrosion science and engineering and a PhD in metallurgy. He was awarded the Johnson Matthey Silver Medal in 1978 for a research paper, based on his MSc Thesis, on potential sources of corrosion in transistor packages. He is a Fellow of the Institute of Materials, Institute of Corrosion and Institute of Metal Finishing. Dr Ray has held posts with Fulmer Research Institute, ITT Semiconductors, British Steel, City of London Polytechnic and University College, London, before joining the Quality Assurance Directorate, Ministry of Defence. He is a member of the British Standards Institutions (BSI) Technical Committees on Electrodeposited and Related Finishes (STC 33), Corrosion Tests (STC 37) and Methods of Test for Metallic and Related Coatings (STC 39); American Society for Testing and Materials (ASTM) Technical Committees on Metallic and Inorganic Coatings, Hydrogen Embrittlement and Corrosion; and the Industrial and Technical Committee of the Institute of Metal Finishing. Since 1983, he has represented the UK as a specialist expert as well as a leader of the UK delegation at the International Standards Organisation's (ISO Technical Committee 107) sub-committees on Methods of Inspection and Co-ordination of Test Methods (SC2), Electrodeposited Coatings and Related Finishes (SC3) and Corrosion Tests for Metallic and Related Coatings (SC7). He is also a specialist representative of the UK to the Working Group (WG 3) of ISO/TC 107/SC3 dealing with hydrogen embrittlement. Dr Ray has published a number of papers on the properties of materials, thickness testing of metallic and inorganic coatings, hydrogen embrittlement, and on the crack initiation characteristics in steel under corrosion fatigue conditions in Metallurgia, Transactions of the Institute of Metal Finishing, British Corrosion Journal, Corrosion Science, Journal of Material Science, ASTM Standardization News and BSI News. He is also the author of a number of standards dealing with surface preparation, electrodeposition, physical vapour deposition, chemical replacement coatings and hydrogen embrittlement. He has lectured extensively on these subjects in addition to standardisation and quality assurance. Table of Contents
