Book Description
This book summarises work done and experience gained over the past three decades in the area of tribology in electrical environments. It takes a close look at behaviour and response characteristics of rolling-element, and hydrodynamic journal & thrust bearings working under the influence of electrical current. Detailed analysis plugs the existing knowledge gaps in the area of tribology in electrical environments. This is because the genesis of intermolecular forces during tribological interaction involves electrostatic attraction or repulsion that creates electro-dynamic, magnetic and exchange forces between atoms. Therefore all tribological phenomena occurring in any interacting system is electrical in nature. - Keep your collection up-to date with the latest volume from Elsevier's Tribology and Interface Engineering Book Series - Includes 'real life' case studies

Book Description
Various factors affect the performance of electrical contacts, including tribological, mechanical, electrical, and materials aspects. Although these behaviors have been studied for many years, they are not widely used or understood in practice. Combining approaches used across the globe, Electrical Contacts: Fundamentals, Applications, and Technology integrates advances in research and development in the tribological, material, and analytical aspects of electrical contacts with new data on electrical current transfer at the micro- and nanoscales. Taking an application-oriented approach, the authors illustrate how material characteristics, tribological behavior, and loading impact the degradation of contacts, formation of intermetallics, and overall reliability and performance. Coverage is divided broadly into three sections, with the first focused on mechanics, tribology, materials, current and heat transfer, and basic reliability issues of electrical contacts. The next section explores applications, such as power connections, electronic connections, and sliding contacts, while the final section presents the diagnostic and monitoring techniques used to investigate and measure phenomena occurring at electrical contact interfaces. Numerous references to current literature reflect the fact that this book is the most comprehensive survey in the field. Explore an impressive collection of data, theory, and practical applications in Electrical Contacts: Fundamentals, Applications, and Technology, a critical tool for anyone investigating or designing electrical equipment with improved performance and reliability in mind.

Book Description
The surface characterizations of engineering materials effects their scratch/abrasion/Mar resistance, coating adhesion/strength, and abrasive wear mechanism. Scratching of Materials and Applications has chapters devoted to direct industrial application and contains some of the important works that are being conducted. Scratch testing of materials has grown extensively since the earlier days of the Mohs Scale for ranking minerals according to their relative scratch resistance. This test has been used on metals, ceramics, glasses, polymers and coatings of various types and thicknesses.The chapters are grouped according to the type of the engineering materials used. The beginning chapters relate mostly to bulk polymers, which are followed by different types of coatings (hard wear resistant to the diamond-like carbon coatings) and finally, chapters on the application of scratching technique to metals and ceramics are included at the end of the book. Thus, the book covers a fairly wide spectrum of engineering materials which are useful to engineers and researchers.* Balances theoretical science with practical application* Demonstrates real-life applications within industry* Written experts in the fields of materials, tribology and surface mechanics

Book Description
Acoustic Emission in Friction is devoted to acoustic, mainly ultrasonic, emission that occurs in friction of machine components. Its crucial novelty is in systematizing the advances in its use for monitoring technical systems, especially in the important nuclear power industry. Written by four well-known experts from the main nuclear research university in Russia, this book covers the following areas: - All the sources of acoustic emission in friction - The theory of acoustic emission - The effects of surface conditions, load and velocity on acoustic emission - The equipment for registration and monitoring of acoustic emission - Unique data from acoustic emission control under various testing conditions in friction units of machinery for nuclear industry machinery There is much emphasis on the comparatively new and rapidly developing tribology of nuclear power engineering. Although a substantial part of the experimental data relates to this specific field of engineering, the universality of the method is shown and its application is possible wherever the field inspection of friction units is necessary. - Calculation expressions describing main characteristics of AE registered in friction units - Describes new set-ups for studying the tribological behaviour of nuclear engineering materials - Presents the theory of the acoustic emission method in friction units

Book Description
Computational elastohydrodynamics, a part of tribology, has existed happily enough for about fifty years without the use of accurate models for the rheology of the liquids used as lubricants. For low molecular weight liquids, such as low viscosity mineral oils, it has been possible to calculate, with precision, the film thickness in a concentrated contact provided that the pressure and temperature are relatively low, even when the pressure variation of viscosity is not accurately modelled in detail. Other successes have been more qualitative in nature, using effective properties which come from the fitting of parameters used in calculations to experimental measurements of the contact behaviour, friction or film thickness. High Pressure Rheology for Quantitative Elastohydrodynamics is intended to provide a sufficiently accurate framework for the rheology of liquids at elevated pressure that it may be possible for computational elastohydrodynamics to discover the relationships between the behaviour of a lubricated concentrated contact and the measurable properties of the liquid lubricant. The required high-pressure measurement techniques are revealed in detail and data are presented for chemically well-defined liquids that may be used as quantitative reference materials.* Presents the property relations required for a quantitative calculation of the tribological behaviour of lubricated concentrated contacts.* Details of high-pressure experimental techniques.* Complete description of the pressure and temperature dependence of viscosity for high pressures.* Some little-known limitations on EHL modelling.

Book Description
TRIBOLOGY AND CHARACTERIZATION OF SURFACE COATINGS The book provides updated information on the friction and wear behavior of coatings used in various industrial applications. Surface modification is a cost-effective process of increasing the life of components so that the whole device need not be changed if the surface is worn out. The tribological behavior of biological implants is currently an active topic and a thorough discussion is one of the book’s features. Tribology and Characterization of Surface Coatings explores key issues which are important in the research and development of surface coatings by providing updated information on friction and wear behavior of coatings used in different industrial applications. It covers the various coating deposition techniques, tribological response of nanocomposite coatings, multilayer hardfacing, and wear testing methods for coatings at nanoscale. The use of nanostructures may alter the tribological, characterization, and mechanical properties of the materials. Thermal spraying is the most widely used technique in industry for the deposition of coatings and their tribological properties need to be determined. This book also includes the recent trends in biotribology and the materials used in implants to counter the abrasive wear. Audience The book will serve as a reference to researchers, scientists, academicians, industrial engineers, and students who work in the fields of materials/polymer science and mechanical engineering. Apart from their applications to aerospace and electronics industries, the coatings are also used in the field of biomedical engineering.
