The book presents a brief analysis of such methods of tribotechnology as the formation of coatings from a filler material on part surfaces owing to friction forces and coating deposition during friction with a lubricant containing plating components. Peculiarities of such methods of tribotechnology as running-in in a lubricant containing nano-sized hard components, which include nanodiamonds are considered in detail. This book examines how tribomechanical modification in the presence of lubricants with nanodiamonds improves tribological properties of friction pairs and prolongs the life of friction units.
