Tribology in Practice Series – serie

Tribology is emerging from the realm of steam engines and crank-case lubricants and becoming key to vital new technologies such as nanotechnology and MEMS. Wear is an integral part of tribology, and an effective understanding and appreciation of wear is essential in order to achieve the reliable and efficient operation of almost any machine or device. Knowledge in the field has increased considerably over recent years, and continues to expand: this book is intended to stimulate its readers to contribute towards the progress of this fascinating subject that relates to most of the known disciplines in physical science. Wear – Materials, Mechanisms and Practice provides the reader with a unique insight into our current understanding of wear, based on the contributions of numerous internationally acclaimed specialists in the field. Offers a comprehensive review of current knowledge in the field of wear.Discusses latest topics in wear mechanism classification.Includes coverage of a wide variety of materials such as metals, polymers, polymer composites, diamonds, and diamond-like films and ceramics.Discusses the chemo-mechanical linkages that control tribology, providing a more complete treatment of the subject than just the conventional mechanical treatments.Illustrated throughout with carefully compiled diagrams that provide a unique insight into the controlling mechanisms of tribology.The state of the art research on wear and the mechanisms of wear featured will be of interest to post-graduate students and lecturers in engineering, materials science and chemistry. The practical applications discussed will appeal to practitioners across virtually all sectors of engineering and industry including electronic, mechanical and electrical, quality and reliability and design.

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.

Due to the rise in petroleum prices as well as increasing environmental concerns, there is a need to develop biochemicals and bioproducts that offer realistic alternatives to their traditional counterparts; this book will address the lack of a centralized resource of information on lubricants and greases from renewable sources, and will be useful to a wide audience in industry and academia. It is based on 20 years of research and development at the UNI-NABL Center, and discusses the various types of vegetable oils available, comparing their characteristics, properties and benefits against those of typical petroleum oils as well as discussing common evaluation tests and giving examples and case studies of successful applications of biobased lubricants and greases. Whilst scientific and engineering research data is included, the book is written in an accessible manner and is illustrated throughout. Focuses on an industrial application of lubrication technology undergoing current explosive growth in the global market.Includes a detailed review of the material benefits of plant-based lubricants that include a better viscosity index and lubricity even at extreme temperatures, lower flammability due to higher flash points and lower pour points.Covers the basic chemistry of vegetable oils as well as their profiles for use in lubricants and greases and environmental benefits.Includes examples and case studies of where vegetable-based lubricants have been successfully employed in industry applications.

Handbook of Surface Treatments and Coatings brings together in a coherent way, for the first time, as much practical information as possible to help with the selection and appropriate use of surface treatments and coatings in mechanical engineering. The selection methods are based on in-service properties and functions required. In this way, a wealth of knowledge and expertise is made easily accessible to a wide audience, including non-specialists.This is an extremely important title in the "Tribology in Practice Series" (TIPS). In order to design and manufacture improved products which have a competitive edge in the global market, it is important to be able to produce surfaces that do not wear; are more resistant to tarnishing and corrosion; and retain their electrical, optical, or thermal properties over a long period of time. It is also of great benefit to be able to simplify product ranges or maintenance requirements, make mechanisms lighter, reduce noise, and enhance the value of strategically or economically advantageous materials.It is now universally acknowledged that surface treatments and coatings have a prominent role to play in this respect. A number of processes of a mechanical, physical, chemical, or electrochemical nature are used to modify the surface properties of materials, in particular their hardness, distribution of residual stresses, composition and structure, topography, and surface energy. Much information on the subject is difficult to access, being very varied in form and content.CONTENTS INCLUDE: Elements of surface mechanics – parameters of frictional contact.Further parameters and definitions.Principal phenomena or surface transformation and wear.The role of surface treatments.Properties, applications, and implementation of surface treatments and coatings.Importance of surface treatments and coatings in tribology.Classification of surface treatments and coatings.Properties and applications of surface treatments and coatings.Materials for tribological use.Principles of surface treatments and coatings processes.Guidelines for selecting and using surface treatments and coatings.

An important volume in the â??Tribology in Practice Seriesâ?? (TIPS). Thoroughly updated and revised, Lubrication and Lubricant Selection is a much-welcomed third edition of this established and successful title. Since the publication of the earlier editions of this title there have been important developments in some aspects of lubricant technology, notably in automotive engine lubricants: for example significant improvements in their expected service life and in fuel economy. A major cause of these changes has been the increasing international concern for the environmental impact of all sorts of technologies, not least lubricant technology. Greater public anxiety for safety and the environment has resulted in new legislation governing such subjects as product liability and environmental protection. This extended and updated edition of Lubrication and Lubricant Selection presents an accurate picture of the current position, particularly with regard to the rapidly changing technical, testing, specification and regulation situation of engine lubricants. The book provides guidance to lubrication practice in industry, with the emphasis on practical application. Specific guidance is given regarding the appropriate selection of lubricants for a wide range of uses. Factors determining the suitability of a lubricant for a particular purpose are described and explained. COMPLETE CONTENTS: Basic principles of lubrication Choice of lubricant type Lubricating oils Selection of lubricating oil Oil supply systems Oil changing and oil conservation Greases and anti-seizes Dry bearings and solid lubrication Gas bearings Sealing of lubricants Lubricant testing and specifications Lubricant monitoring Lubricant handling and storage Health and safety
