This book presents the latest research in ultrathin carbon-based protective overcoats for high areal density magnetic data storage systems, with a particular focus on hard disk drives (HDDs) and tape drives. These findings shed new light on how the microstructure and interfacial chemistry of these sub-20 nm overcoats can be engineered at the nanoscale regime to obtain enhanced properties for wear, thermal and corrosion protection – which are critical for such applications. Readers will also be provided with fresh experimental insights into the suitability of graphene as an atomically-thin overcoat for HDD media. The easy readability of this book will appeal to a wide audience, ranging from non-specialists with a general interest in the field to scientists and industry professionals directly involved in thin film and coatings research.

This volume entitled "Protective Coatings and Thin Films : Synthesis, Characterization and Applications" contains the Proceedings of the NATO Advanced Research Workshop (ARW) held in Alvor, Portugal from May 30 to June 5, 1996. This NATO-ARW was an expert meeting on the surface protection and modification of solid materials subjected to interactions with the environment. The meeting attracted 10 key speakers, 40 contributing speakers and 3 observers from various countries. The existing knowledge and current status of the science and technology related to protective coatings and thin films were assessed through a series of oral presentations, key notes (titles underlined in the volume content) and contributed papers distributed over various sessions dealing with: (a) plasma-assisted physical and chemical vapor deposition processes to enhance wear and corrosion protection of materials, (b) low friction coatings operating in hostile environment (vacuum, space, extreme temperatures, . . . ), (c) polymer films for protection against mechanical damage and chemical attack, (d) characterization of the structure of films and correlations with mechanical properties, (e) wear and corrosion resistant thermal spray coatings, (f) functional gradient ceramic/metallic coatings produced by high energy laser beam and energetic deposition processes for high temperature applications, (g) protective coatings for optical systems, and (h) ion beam assisted deposition of coatings for protection of materials against aqueous corrosion.

This handbook is a useful aid for anyone working to achieve more effective lubrication, better control of friction and wear, and a better understanding of the complex field of tribology. Developed in cooperation with the Society of Tribologists and Lubrication Engineers and containing contributions from 74 experts in the field, the Tribology Data Handbook covers properties of materials, lubricant viscosities, and design, friction and wear formulae. The broad scope of this handbook includes military, industrial and automotive lubricant specifications; evolving areas of friction and wear; performance and design considerations for machine elements, computer storage units, and metal working; and more. Important guidelines for the monitoring, maintenance, and failure assessment of lubrication in automotive, industrial, and aircraft equipment are also included. Current environmental and toxicological concerns complete this one-stop reference. With hundreds of figures, tables, and equations, as well as essential background information explaining the information presented, this is the only source you need to find virtually any tribology information.

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.

An important resource for students, engineers and researchers working in the area of thin film deposition using physical vapor deposition (e.g. sputtering) for semiconductor, liquid crystal displays, high density recording media and photovoltaic device (e.g. thin film solar cell) manufacturing. This book also reviews microelectronics industry topics such as history of inventions and technology trends, recent developments in sputtering technologies, manufacturing steps that require sputtering of thin films, the properties of thin films and the role of sputtering target performance on overall productivity of various processes. Two unique chapters of this book deal with productivity and troubleshooting issues. The content of the book has been divided into two sections: (a) the first section (Chapter 1 to Chapter 3) has been prepared for the readers from a range of disciplines (e.g. electrical, chemical, chemistry, physics) trying to get an insight into use of sputtered films in various devices (e.g. semiconductor, display, photovoltaic, data storage), basic of sputtering and performance of sputtering target in relation to productivity, and (b) the second section (Chapter 4 to Chapter 8) has been prepared for readers who already have background knowledge of sputter deposition of thin films, materials science principles and interested in the details of sputtering target manufacturing methods, sputtering behavior and thin film properties specific to semiconductor, liquid crystal display, photovoltaic and magnetic data storage applications. In Chapters 5 to 8, a general structure has been used, i.e. a description of the applications of sputtered thin films, sputtering target manufacturing methods (including flow charts), sputtering behavior of targets (e.g. current - voltage relationship, deposition rate) and thin film properties (e.g. microstructure, stresses, electrical properties, in-film particles). While discussing these topics, attempts have been made to include examples from the actual commercial processes to highlight the increased complexity of the commercial processes with the growth of advanced technologies. In addition to personnel working in industry setting, university researchers with advanced knowledge of sputtering would also find discussion of such topics (e.g. attributes of target design, chamber design, target microstructure, sputter surface characteristics, various troubleshooting issues) useful. . Unique coverage of sputtering target manufacturing methods in the light of semiconductor, displays, data storage and photovoltaic industry requirements Practical information on technology trends, role of sputtering and major OEMs Discussion on properties of a wide variety of thin films which include silicides, conductors, diffusion barriers, transparent conducting oxides, magnetic films etc. Practical case-studies on target performance and troubleshooting Essential technological information for students, engineers and scientists working in the semiconductor, display, data storage and photovoltaic industry
