Abstract
The invention relates to a method for coating a substrate, a coating system for carrying out the method, and a coated body. In a first method step, the substrateis pretreated in a ion etching process. In a second method step, a first coating layerwith a thickness of 0.1 μm to 6 μm is deposited on the substrateby means of a PVD process. In order to achieve a particularly high-quality and durable coating, the surface of the first coating layeris treated by means of an ion etching process in a third method step, and an additional coating layerwith a thickness of 0.1 μm to 6 μm is deposited on the first coating layerby means of a PVD process in a fourth method step. The coated body comprises at least two coating layerswith a thickness of 0.1 μm to 6 μm on a substrate, wherein an interface region formed by ion etching is arranged between the coating layers
