Quantum Effects in Tribology is devoted to the study of quantum foundations of materials friction interaction and evolutionary formation of tribosystem's operating parameters. At the start of the book, large consideration is given to the analysis of the existing diversity of friction, wear, and lubrication models and their relationship with each other, as well as to the quantum nature of the measurement process and the wave function reduction caused by the act of measurement. Consideration of measurement as a process of defining the output parameters of tribosystem is carried out with the apparatus of second quantization and conceptions associated with non-local quantum effects. Such an approach makes it possible not only to take another look to the evolution of tribosystems but discover previously unknown regularities of friction. The book is intended for professionals working in the field of tribology, but will be also useful for graduate students specializing in the theory of friction and quantum physics.
