Abstract
A method for improving the performance and/or service life of pistons, wherein at least one PVD coating source includes a target. The coating source is arranged on a wall of the coating chamber and is periodically operated. The target surface to be evaporated is positioned parallel to the vertical axis and the surface sections to be coated are positioned in front of the target surface in the coating region using a holding device. The substrate receiving area is rotated periodically about the rotational axis of the substrate receiving area by a rotary system which is a coupling system, or is arranged on the coupling system, or is a part of the coupling system. The rotational axis and the vertical axis form an angle which is larger than 10° and smaller than 180° such that the coating material reaches each part of the individual surface sections at least once.
