This monograph takes a new look at tribology with its basic concepts of friction and wear using the example of lubricating greases. The consideration of the phenomenon of occurring instabilities and the introduction of the entropy concept into lubricating grease tribology provide a new perspective on known phenomena.

The second part of this book presents a wide range of experimental possibilities for investigating lubricating greases.

Prof. Dr. Erik Kuhn: first studied construction, later welding technology and tribotechnology, doctorate in tribology, since 1991 professor at HAW Hamburg and head of the Tribology Research Center, teaches at various colleges and universities, since 2005 organizer of the Arnold Tross Colloquium (Tribology)
