The surface properties of a bulk material are not accepted totally and independently. The tribology is the most important field that comprises the component design with static and dynamic relations for a reliability and performance. Hence, it is believed that the surface contacts, atmosphere, and lubrication significantly change the wear resistance of the material surface.
Tribology encompasses a wide range of problems related to friction, wear and lubrication. Overcoming such problems has played a central role in the advancement of mankind, from moving massive ancient stone blocks and constructions and the invention of the wheel through to the development of important machinery components in the industrialised society such as bearings, gears, seals, liners, cylinders, tools, etc. Today the movement of the piston in the cylinder of a car engine is enabled by the shear of a well controlled thin lubricating oil film, the digital data transmission in computers depends crucially on the tribological air-bearing solution in the magnetic storage system and the successful function of replacement hip joints is dependent upon on advanced wear and lubrication control. The level of tribological knowledge and its application influences society in several ways. Optimised friction in industry and transportation results in energy savings, controlled wear and lubrication improves the efficiency and quality of production and results in increased reliability and safety, reduced costs due to down-time and reduced environmental risks and impact. It has been estimated that about half of all the energy produced is used to overcome friction and that almost half of all the products produced in the industrialised countries are to replace worn out products. Many problems related to tribology were long neglected, principally because of their multidisciplinary character, which meant that they did not fit well into any of the traditional scientific disciplines.
Friction and Wear
Friction Wear Lubrication, Volume 3: Tribology Handbook provides comprehensive and specific information regarding the design and troubleshooting of tribological devices. The topics covered include the classes of guide ways; assembly components of cylinders and pistons; general principles of sealing; and classification and design of dynamic friction devices. This book also discusses the frictional interaction and displacement in stationary joints; friction and wear of tires or vehicle wheels; and friction and wear of metal-cutting and metal-forming tools. The flexible drive elements, friction and wear of electric contacts are also explained. A list of scientific and mechanical notations is provided at the end, including detailed references in each chapter.

Tribology: Friction and Wear of Engineering Materials, Second Edition covers the fundamentals of tribology and the tribological response of all classes of materials, including metals, ceramics, and polymers. This fully updated and expanded book maintains its core emphasis on friction and wear of materials, but now also has a strengthened coverage of the more traditional tribological topics of contact mechanics and lubrication. It provides a solid scientific foundation that will allow readers to formulate appropriate solutions when faced with practical problems, as well as to design, perform and interpret meaningful tribological tests in the laboratory. Topics include the fundamentals of surface topography and contact mechanics, friction, lubrication, and wear including tribo-corrosion , as well as surface engineering, selection of materials and design aspects. The book includes case studies on bearings, automotive tribology, manufacturing processes, medical engineering and magnetic data storage that illustrate some of the modern engineering applications in which tribological principles play vital roles. Each chapter is complemented by a set of questions suitable for self-study as well as classroom use. This book provides valuable material for advanced undergraduates and postgraduates studying mechanical engineering, materials science and other technical disciplines, and will also be a useful first reference point for any engineer or scientist who encounters tribological issues.
Friction and wear of materials
Friction and Wear of Materials. Ernest Rabinowicz. Friction and Wear of Materials Second Edition Written by one of the world's foremost authorities on friction, this classic book offers a lucid presentation of the theory of mechanical surface interactions as it applies to friction, wear, adhesion, and boundary lubrication. To aid engineers in design decisions, Friction and Wear of Materials evaluates the properties of materials which, under specified conditions, cause one material to function better as a bearing material than another. Featured also are thorough treatments of lubricants and the sizes and shapes of wear particles.

Слова приятеля его очень удивили. Дело в том, что АНБ не только существовало, но и считалось одной из самых влиятельных правительственных организаций в США и во всем мире. Уже больше полувека оно занималось тем, что собирало электронные разведданные по всему миру и защищало американскую секретную информацию. О его существовании знали только три процента американцев. - АНБ, - пошутил приятель, - означает Агентство, которого Никогда не Было. Со смешанным чувством тревоги и любопытства Беккер принял приглашение загадочного агентства.
Три минуты! - послышался крик. - А сверхкритическая масса? - предложила Соши. - Тут сказано, что сверхкритическая масса плутония составляет тридцать пять и две десятых фунта. - Вот именно! - крикнул Джабба. - Посмотрите уран. Его сверхкритическую массу. - М-м… сто десять фунтов, - сказала Соши.
