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.

Coatings are tested to confirm compliance with specifications, to monitor the operation of a coating process, and to evaluate coatings for various services. The ability of a coating to perform as intended usually depends on several characteristics, and the testing of a coating usually involves several different tests. At first glance the nature of a characteristic that is being tested may seem clear and the results of a test may seem to be unambiguous, however, the nature of a characteristic my be more complex than realized and the ability of a test to measure the characteristic may be less than expected. The members of the ASTM Committee B-8 on Metallic and Inorganic Coatings felt it was desirable to organize a symposium on the testing of the metallic and inorganic coatings so as to bring these problems to the attention of practitioners. This publication is based on the symposium, which was presented in Chicago on April 14 and 15, 1986.

The surface coating field is a rapidly developing area of science and technology that offers new methods and techniques to control friction and wear. New coating types are continually being developed and the potential applications in different industrial fields are ever growing, ranging from machine components and consumer products to medical instruments and prostheses. This book provides an extensive review of the latest technology in the field, addressing techniques such as physical and chemical vapour deposition, the tribological properties of coatings, and coating characterization and performance evaluation techniques. Eleven different cases are examined in close detail to demonstrate the improvement of tribological properties and a guide to selecting coatings is also provided. This second edition is still the only monograph in the field to give a holistic view of the subject and presents all aspects, including test and performance data as well as insights into mechanisms and interactions, thus providing the level of understanding vital for the practical application of coatings. * An extensive review of the latest developments in the field of surface coatings * Presents both theory and practical applications * Includes a guide for selecting coatings

Magnetic recording is presently a $50 billion industry. It spans audio, video, and digi tal applications in the form of tapes and disks. The industry is expected to grow by a factor of five or more in the next decade. This growth will be accompanied by dramatic improvements in the technology, and the potential exists for magnetic-recording den sities to improve by at least one order of magnitude! Magnetic-recording process is accomplished by relative motion between a mag netic head and a magnetic medium. Types of magnetic media for digital recording are: flexible media (tapes and floppy disks) and rigid disks. Physical contact between head and medium occurs during starts and stops and hydrodynamic air film develops at high speeds. Hying heights (mean separation between head and medium) are on the order of 0. 1 micrometer comparable to surface roughness of the mating members. Need for higher and higher recording densities requires that surfaces be as smooth as possible and flying heights be as low as possible. Smoother surfaces lead to increased static/ kinetic friction and wear. In the case of magnetic tapes, in order to have high bit capac ity for a given size of a spool, we like to use as thin a tape substrate as possible. Thinner tapes are prone to local or bulk viscoelastic deformation during storage. This may lead to variations in head-tape separations resulting in problems in data reliability.
