Available in PDF, EPUB and Kindle. Book excerpt: Tribology is the study of friction, wear, and lubrication of surfaces in relative motion. In mechanical components, friction and wear lead to loss of energy efficiency. Lubricants control friction and wear by creating a film that separates contacting surfaces, which consequently reduces energy consumption and prolongs machine life. The effectiveness of a lubricating film is highly dependent on the physical and chemical properties as well as the composition of the lubricant used. Minor changes in chemical properties or composition can significantly influence the functionality of the lubricating film. Therefore it is necessary to understand the factors and mechanisms that influence the performance of lubricants at the molecular level. The aim of this thesis is to investigate the surface and bulk properties of liquid lubricants using molecular dynamics (MD) simulation. This thesis is divided into two parts, where Part I focuses on understanding the properties of lubricated surfaces, and Part II explores the properties of bulk lubricants, specifically the pressure-viscosity and temperature-viscosity response of lubricating fluids. We explored the surface coverage and stability of thin functionalized polymer films using coarse-grain models, where we quantified the change in disjoining pressure with film thickness. We also studied the mechanochemical process occurring at boundary lubricated sliding interfaces and demonstrated that a distribution of forces is present at the sliding interface. Only a small percentage of the molecules at the sliding interface experienced forces large enough to initiate mechanochemical reactions. Next, we developed a novel method for predicting the pressure-viscosity response of fluids using an empirical equation and MD-predicted material properties. Using this method, the pressure-viscosity response of fluids was predicted from the variation of volume with pressure, which can be obtained relatively easily using atomic simulations. The temperature-viscosity response of liquid lubricants was also investigated to understand the mechanisms underlying the functionality of viscosity index improving (VII) polymers. Here, we studied the coil expansion mechanism of typical VII chemistries and found that the presence of specific molecular features influences the functionality of the polymer. In general, this work provides an in-depth analysis of several key properties that govern the functionality of surface and bulk lubricants. A clear understanding of functionality can lead to better lubricating capabilities through the design of novel application-specific lubricants, thus leading to an increase in energy efficiency and decrease in energy consumption.

Available in PDF, EPUB and Kindle. Book excerpt: Although it is widely recognized that friction, wear and lubrication are linked together in a single interdisciplinary complex of scientific learning and technological practice, fragmented and specialized approaches still predominate. In this book, the authors examine lubrication from an interdisciplinary viewpoint. They demonstrate that once the treatment of lubrication is released from the confines of the fluid film concept, this interdisciplinary approach comes into full play. Tribological behavior in relation to lubrication is then examined from two major points of view: one is mechanical, not only with respect to the properties and behavior of the lubricant but also of the surfaces being lubricated. The other is chemical and encompasses the chemistry of the lubricant, the surfaces and the ambient surroundings. It is in the emphasis on the interaction of the basic mechanical and chemical processes in lubrication that this book differs from conventional treatments.

Available in PDF, EPUB and Kindle. Book excerpt: The technology involved in lubrication by nanoparticles is a rapidly developing scientific area and one that has been watched with interest for the past ten years. Nanolubrication offers a solution to many problems associated with traditional lubricants that contain sulphur and phosphorus; and though for some time the production of nanoparticles was restricted by the technologies available, today synthesis methods have been improved to such a level that it is possible to produce large quantities relatively cheaply and efficiently. Nanolubricants develops a new concept of lubrication, based on these nanoparticles, and along with the authors’ own research it synthesises the information available on the topic of nanolubrication from existing literature and presents it in a concise form. Describes the many advantages and potential applications of nanotechnology in the tribological field. Offers a full review of the state-of-the-art as well as much original research that is yet unpublished. Includes sections on boundary lubrication by colloïdal systems, nanolubricants made of metal dichalcogenides, carbon-based nanolubricants, overbased detergent salts, nanolubricants made of metals and boron-based solid nanolubricants and lubrication additives. Authored by highly regarded experts in the field with contributions from leading international academics. Nanolubricants will appeal to postgraduate students, academics and researchers in mechanical engineering, chemical engineering and materials science. It should also be of interest to practising engineers with petroleum companies and mechanical manufacturers.

Download or read book Tribology of Abrasive Machining Processes written by Ioan D. Marinescu and published by William Andrew. This book was released on 2012-12-07 with total page 602 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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
