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

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

Applied Plastics Engineering Handbook covers both polymer basics - helpful to bring readers quickly up to speed if they are not familiar with a particular area of plastics processing - and recent developments - enabling practitioners to discover which options best fit their requirements. Each chapter is an authoritative source of practical advice for engineers, providing authoritative guidance from experts that will lead to cost savings and process improvements. Throughout the book, the focus is on the engineering aspects of producing and using plastics. The properties of plastics are explained along with techniques for testing, measuring, enhancing and analyzing them. Materials and additives are described as well as their characteristics and effects. The technologies and machinery used in processing operations are covered with reference to product design. And recent developments in a cross-section of applications demonstrate in a pragmatic way, the opportunities as well as the limitations of plastics. • Practical introductions to both core topics and new developments make this work equally valuable for newly qualified plastics engineers seeking the practical rules-of-thumb they don't teach you in school, and experienced practitioners evaluating new technologies or getting up to speed on a new field. • The depth and detail of the coverage of new developments enables engineers and managers to gain knowledge of, and evaluate, new technologies and materials in key growth areas such as biomaterials and nanotechnology. • This highly practical handbook is set apart from other references in the field, being written by engineers for an audience of engineers and providing a wealth of real-world examples, best practice guidance and rules-of-thumb.

An important aspect of engineering surfaces is that they need to be multifunctional as designs of machine components require cheaper, lighter, smarter, longer-wearing, and more environmentally friendly surfaces that see applications that are hotter, faster, highly pressurized, and exposed to other increasingly hostile environments. This can be achieved by use of modern advanced materials and coatings, which now usually are coated systems. This is a challenging area as usually there is antagonism between obtaining low friction and low wear as well as between high corrosion resistance and low wear. This book covers the increasingly important aspect for engineering surfaces to be multifunctional with a focus on tribological applications. It captures the state of the art regarding the emerging needs for multifunctional surface design for controlling wear, friction, and corrosion, as well as having decorative, self-healing, and/or self-sensing capabilities. It focuses on coatings and materials that include CVD diamond, diamond-like carbon, and multilayered and functionally graded systems for a range of engineering applications including machine tools, orthopedic joints, aero-engines/gas turbines, automotive engines, glass windows and walls, and offshore and marine sectors. It is a unique book as it discusses a range of wet- and dry-deposited coatings and multifunctional materials not often seen in one publication. It allows the reader to understand a wide range of design concepts and what is possible to achieve by current surface engineering techniques.
