Friction and wear can be affected not only by materials, lubricants and the running-in, but also by final cutting processes such as grinding, honing or lapping. Except for changes of topography the cutting procedure leads also to changes of the chemical composition as well as of the crystalline structure of the near-surface material. By suitable choice of the tool, process parameters and coolant critical defect structures are avoided and a surface conditioning can be achieved. During running-in such an optimal regime enables high friction power input, mechano-chemical intermixing of the near-surface material as well as the generation of nano-crystalline structures. This results in low friction and wear during running-in and subsequent operation.
