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

Your Guide to Advanced Cold Spray Technology Cold Gas Dynamic Spray centers on cold gas dynamic spray (or cold spray—CS) technology, one of the most versatile thermal spray coating methods in materials engineering, and effectively describes and analyzes the main trends and developments behind the spray (coating) techniques. The book combines theory with practice to enable the reader to deeper understand the CS coatings as well as their structures and properties, and describes the state of the art in CS technology with an emphasis on all major components of the cold spray process. This book begins with an introduction to CS spray and goes on to thoroughly explain the process. It describes the different powder synthesis methods and equipment currently used, and defines the CS coating microstructure, characterization methods, and properties of CS coatings. The authors present a comprehensive approach that highlights grit blasting and cold spraying as well as the hybrid CS-sintering technology that offers integrity of microstructure, compositional homogeneity, and mechanical property levels equal to (and frequently better than) those of the wrought counterpart. The book largely covers the basic principles of CS technology and also includes: A brief survey of thermal spray methods The basic principles of plasticity theory A description of the CS equipment, the nozzle design, and the geometry of a CS gun Coverage of the microstructural and mechanical properties of CS metals and alloys A detailed analysis of aircraft component repair using GS An overview of the economic aspects of CS applications. Cold Gas Dynamic Spray explains how cold gas dynamic spray works and what it can do, and is intended for engineering professionals working with sprays and coatings in the industry as well as graduate student specializing in material science, mechanical, automotive, aerospace, and chemical engineering.

This collection of fully peer-reviewed papers were presented at the 26th Leeds-Lyon Tribology Symposium which was held in Leeds, UK, 14-17 September, 1999. The Leeds-Lyon Symposia on Tribology were launched in 1974, and the large number of references to original work published in the Proceedings over many years confirms the quality of the published papers. It also indicates that the volumes have served their purpose and become a recognised feature of the tribological literature. This year's title is 'Thinning Films and Tribological Interfaces', and the papers cover practical applications of tribological solutions in a wide range of situations. The evolution of a full peer review process has been evident for a number of years. An important feature of the Leeds-Lyon Symposia is the presentation of current research findings. This remains an essential feature of the meetings, but for the 26th Symposium authors were invited to submit their papers for review a few weeks in advance of the Symposium. This provided an opportunity to discuss recommendations for modifications with the authors.
