Many people, including those involved in the manufacturing, marketing and selling of lubricants, believe that blending lubricants is simply a matter of putting one or more base oils and several additives into a tank of some kind and stirring them around to mix them. Blending lubricants that meet customers' demands requires much more than this. The correct ingredients of the right quality need to be used in precisely controlled quantities. The ingredients need to be tested prior to blending and the finished products need to be tested following blending. The ingredients need to be stored and mixed under carefully controlled conditions. The finished lubricants need to be stored and packaged carefully and then delivered to customers correctly. This book discusses all of these issues, describes the different types of equipment used to blend lubricants, provides guidance on how best to use this equipment, and offers tips and techniques to help to avoid problems. It focuses on liquid lubricants. Greases are not discussed, as their manufacture involves very different manufacturing procedures compared with those concerned with liquid lubricants. The book starts with descriptions and discussion of the properties and characteristics of the main types of mineral and synthetic base oils, as well as the properties and characteristics of the main types of additives that are used in lubricant formulations. Criteria and methodologies used to design both new and upgraded blending plants are covered next. The types and operation of the equipment used in lubricant blending plants are described and discussed, together with a chapter on how to avoid problems before, during, and after blending. Testing and analysis of base oils, additives, and blended lubricants are covered in two separate chapters. Procedures for quality control and quality management in lubricant blending plants are also discussed in two separate chapters. Types of packages for lubricants are reviewed, together with methods for filling packages and methods for transporting lubricants in bulk. The storage of lubricants and supply chain management is also covered in depth.

Turbulence in plasma surface interaction holds crucial uncertainties for its impact on material erosion in the operation of fusion reactors. In this thesis, the design, development and operation of a Thomson scattering diagnostic and its novel implementation with fast visual imaging created a versatile tool to investigate intermittently occuring plasma oscillations. Specifically, ballistic transport events in the plasma edge, constituting turbulent transport, have been targeted in this thesis. With the help of a custom photon counting algorithm, the conditional averaging technique was applied on Thomson scattering for the first time to allow spatial and pseudo-time-resolved measurements. Since plasma turbulence and the emerging transport phenomena are comparable in most magnetized devices, the diagnostic development and the results from the linear plasma device PSI-2 are useful for an implementation of similar techniques in larger fusion experiments. Furthermore, the obtained results indicate a strong enhancement of erosion with turbulent transport and thus underline the importance of dedicated experiments investigating plasma turbulence in the framework of erosion in future fusion reactors.

Friction, lubrication, adhesion, and wear are prevalent physical phenomena in everyday life and in many key technologies. This book incorporates a bottom-up approach to friction, lubrication, and wear into a versatile textbook on tribology. This is done by focusing on how these tribological phenomena occur on the small scale - the atomic to the micrometer scale - a field often called nanotribology. The book covers the microscopic origins of the common tribological concepts of roughness, elasticity, plasticity, friction coefficients, and wear coefficients. Some macroscale concepts (like elasticity) scale down well to the micro- and atomic-scale, while other macroscale concepts (like hydrodynamic lubrication) do not. In addition, this book also has chapters on topics not typically found in tribology texts: surface energy, surface forces, lubrication in confined spaces, and the atomistic origins of friction and wear. These chapters cover tribological concepts that become increasingly important at the small scale: capillary condensation, disjoining pressure, contact electrification, molecular slippage at interfaces, atomic scale stick-slip, and atomic bond breaking. Throughout the book, numerous examples are provided that show how a nanoscale understanding of tribological phenomena is essential to the proper engineering of important modern technologies such as MEMS, disk drives, and nanoimprinting. For the second edition, all the chapters have been revised and updated to incorporate the most recent advancements in nanoscale tribology. Another important enhancement to the second edition is the addition of problem sets at the end of each chapter.

This book presents the research advances in the science of measurement, giving special focus to the field of machining and tribology.
