This book focuses on the triboemission of low-energy electrons from the freshly generated surface. These electrons play the most crucial role in the chemical reactions at the tribological interface. New models and TIP (thermodymanics of irreversible processes) describe in detail the behavior of emitted electrons which lower the activation energy of the chemical reactions. This book also highlights tribocatalysis phenomena as examples of the lowering of the activation energy. A book titled Tribocatalysis has never been published before this.
KEY FEATURES: Assists scientists, engineers and researchers in the development of a new high performance lubricant·An essential review of the state of knowledge in tribochemistry.The first book published related to tribochemistry oilsDESCRIPTION:This latest title takes a new and unconventional look at engine oil as a micellar system. It is the first book of its kind to focus on the tribochemistry of oils and is thus an essential resource to practicing scientists and engineers in the petroleum industry and to all interested in the development of a superior high performance lubricant. Guaranteeing its broad appeal the book gives an invaluable review of the state of knowledge in the rapidly growing area of tribochemistry. The concept of miscelles is clearly explained along their application to stimulate the quality of engine oil, improve fuel efficiency and maintain adequate wear protection formulation. This represents a fresh approach to the formation of anti-wear tribofilms. A new look at engine design trends is given further assisting engineers in the development of a superior lubricant
Tribology is usually defined as "the science and technology of interacting surfaces in relative motion". It includes the research and application of principles of friction, wear, lubrication and design. Green tribology involves tribological aspects of environmental and biological impacts. This multidisciplinary field of science and technology is very important for the development of new products in mechanics, materials, chemistry, life sciences and by extension for all modern industry. The current volume aims to provide recent information on progress in green tribology. Chapter 1 provides information on tribological materials (an eco-sustainable perspective), while chapter 2 is dedicated to preparation and tribology performance of bio-based ceramic particles from rice waste and chapter 3 describes tribological behavior and tribochemistry of Ti3SiC2 in water and alcohols. Chapter 4 contains information on modelling and analysis of the oil-film pressure of a hydrodynamic journal bearing lubricated by nano based bio-lubricants using a D-optimal design. Finally, chapter 5 is dedicated to wear performance of oil palm seed fibre reinforced polyester composite aged in brake fluid solutions. The current volume can be used as a research book for final undergraduate in engineering courses or as a topic on green tribology at postgraduate level. This book can also serve as useful reference for academics, researchers, mechanical, materials, environmental and manufacturing engineers, professionals green tribology and related industries.
This volume provides a comprehensive introduction to the scientific and technical aspects of tribochemistry, a field concerned with the chemical reactions initiated by mechanical energy. The relevant theoretical background, recent innovations and results, and the possibilities of expanding industrial applications are covered.
Leading readers through an extensive compilation of surface modification reactions and processes for specific tribological results, this reference compiles detailed studies on various residual stresses, reaction processes and mechanisms, heat treatment methods, plasma-based techniques, and more, for a solid understanding of surface structural changes that occur during various engineering procedures. This unique book explores topics previously ignored in other texts on surface engineering and tribology, offers guidelines for the consideration and design of wear life and frictional performance, and sections on laser impingement and nanometer scale surface modification.
The main goal in preparing this book was to publish contemporary concepts, new discoveries and innovative ideas in the field of surface engineering, predominantly for the technical applications, as well as in the field of production engineering and to stress some problems connected with the use of various surface processes in modern manufacturing of different purpose machine parts. This book is an attempt to introduce science into the study of surface treatment processes. Tribology offers a good approach for describing abrasive machining and coating processes and offers the ability to predict some of the outputs of the processes. The study of friction, forces, and energy explores the importance of the various factors which govern the stresses and deformations of abrasion. The effects of grain shape, depth of penetration, and lubrication on the process forces are explored. The tribology of nanostructured surfaces involves many fundamental and scientific issues. More importantly, it has tremendous applications in industries. It is a powerful tool to regulate friction, adhesion, and wetting of surfaces by altering their geometric textures and material compositions at the nanoscale, and, hence, to control the tribological performance of the engineering surfaces.
In spite of the practical importance of the friction, wear and lubrication of elastomers, limited literature is available on this topic. Addressing these needs, this book will give readers a complete understanding of rubber tribology and the key developments in this field over the last ten years. For the first time new and important achievements such as theories of rubber abrasion and surfacial mechanochemical effects of rubber wear are presented. The book pays special attention to the principles of rubber wear – a clear understanding of which is essential for those striving towards further increasing the working life of rubber.* Comprehensively and systematically covers main points of rubber tribology* The original choice of contents informs readers of the latest developments in the field*Meeting the needs of various readers - researchers, engineers, technicians, graduates
This book draws upon the science of tribology to understand, predict and improve abrasive machining processes. Pulling together information on how abrasives work, the authors, who are renowned experts in abrasive technology, demonstrate how tribology can be applied as a tool to improve abrasive machining processes. Each of the main elements of the abrasive machining system are looked at, and the tribological factors that control the efficiency and quality of the processes are described. Since grinding is by far the most commonly employed abrasive machining process, it is dealt with in particular detail. Solutions are posed to many of the most commonly experienced industrial problems, such as poor accuracy, poor surface quality, rapid wheel wear, vibrations, work-piece burn and high process costs. This practical approach makes this book an essential tool for practicing engineers. - Uses the science of tribology to improve understanding and of abrasive machining processes in order to increase performance, productivity and surface quality of final products - A comprehensive reference on how abrasives work, covering kinematics, heat transfer, thermal stresses, molecular dynamics, fluids and the tribology of lubricants - Authoritative and ground-breaking in its first edition, the 2nd edition includes 30% new and updated material, including new topics such as CMP (Chemical Mechanical Polishing) and precision machining for micro-and nano-scale applications
