This thesis investigates the tribological viability of bio-based base stock to which different nanoparticles were incorporated for engine piston-ring-cylinder-liner interaction. It determines experimentally the effects of lubricating oil conditions (new and engine-aged) on the friction and wear of the materials used for piston rings and cylinder liners. The specific base stock examined was a trimethylolpropane (TMP) ester derived from palm oil, and the nanoparticles were used as additives to obtain tribologically enhanced bio-based lubricants. The overall analysis of the results demonstrated the potential of nanoparticles to improve the tribological behavior of bio-based base stock for piston-ring-cylinder-liner interaction.

Diamond-like carbons (DLCs) display a number of attractive properties that make them versatile coating materials for a variety of applications, including extremely high hardness values, very low friction properties, very low gas permeability, good biocompatibility, and very high electrical resistivity, among others. Further research into this material is required to produce hydrogen-free DLC films and to synthesize it together with other materials, thereby obtaining better film properties. Diamond-Like Carbon Coatings: Technologies and Applications examines emerging manufacturing technologies for DLCs with the aim of improving their properties for use in practical applications. Discusses DLC coatings used in mechanical, manufacturing, and medical applications Details recent developments in the novel synthesis of DLC films Covers advances in understanding of chemical, structural, physical, mechanical, and tribological properties for modern material processing Highlights methods to yield longer service life Considers prospects for future applications of emerging DLC technologies This work is aimed at materials science and engineering researchers, advanced students, and industry professionals.

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.

A Comprehensive Review of Developing Environmentally Friendly Lubricants A push from environmentally savvy consumers along with recent changes in governmental regulations have paved the way for a marketplace of products with high levels of environmental performance. Fueled by the growing demand for biobased lubricants, Environmentally Friendly and Biobased Lubricants highlights the development of environmentally friendly additives that are compatible with environmental regulations and describes the approaches being used in this emerging area. Derived from research topics shared over the years at various technical sessions of the Society of Tribologists and Lubrication Engineers (STLE) Annual Meetings, the book includes a critical assessment of gaps and weaknesses in the field of environmentally friendly fluids and biobased lubricants. Each chapter is written by authors selected from the environmentally friendly fluids and biobased lubricants sessions of STLE and also incorporates input from prominent researchers invited to take part in the book. Expert contributors discuss the control, production, usage, and disposal of lubricants; factor in related policies, laws, and regulations around the world; and include case studies demonstrating the uses and values of commercially viable biobased lubricants. The book is divided into five sections that cover advanced environmentally friendly base oils and feedstocks, biobased hydraulic lubricants and biodegradability, chemically/enzymatically modified environmentally friendly base oils, vegetable oil–based environmentally friendly fluids, and additives for environmentally friendly fluids.

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.
