Tribology includes the research and application of principles of friction, wear, and lubrication. Frictional interactions in small scale are becoming increasingly important for the development of new products in mechanics, chemistry, electronics, life sciences, sensors, and by extension for all modern technology. In addition, surface engineering is a truly interdisciplinary topic in materials science that deals with the surface of solid matter. This book provides discussion and the exchange of information on all aspects of tribology and surface engineering in regards to modern industry.
