| Summary |
"Concise, accessible introduction to lubricants for engineers, technicians and researchers who are not experts in lubricant chemistry or tribology. Lubricants: Properties and Performance provides an easy to understand overview of tribology and lubricant chemistry, and bridges the gap between the two areas. The first part of the book is theoretical and provides an introduction to tribological contact, friction, wear and lubrication, as well as the basic concepts regarding properties and the most commonly made analyses on lubricants. Base fluids and their properties and common additives used in lubricants are also covered. The second part of the book is hands-on and introduces the reader to the actual formulations and the evaluation of their performance. Different applications and their corresponding lubricant formulations are considered and tribological test methods are discussed. Finally used oil characterisation and surface characterisation are covered which give the reader an introduction to different methods of characterising used oils and surfaces, respectively. Easy to understand overview of the properties and performance of lubricants Combines chemistry and tribology of lubricants into one unified approach Covers the fundamental theory, describing lubricant properties as well as base fluids and additives Contains practical information on the formulations of lubricants and evaluates their performance Considers applications of lubricants in hydraulics, gears and combustion engines"-- Provided by publisher |
