Title:
MULTI-LAYER COATING
Document Type and Number:
WIPO Patent Application WO/2021/048136
Kind Code:
A3
Abstract:
The invention relates to a method for coating a substrate (40), a coating system for carrying out the method and a coated body. In a first method step (62), the substrate (40) is pretreated in an ion etching process. In a second method step (64), a first coating layer (56a) with a thickness of 0.1µm to 6µm is deposited on the substrate (40) by means of a PVD process. In order to achieve a particularly high-quality and durable coating (50), the surface of the first coating layer (56a) is treated by means of an ion etching process in a third method step (66), and an additional coating layer (56b) with a thickness of 0.1µm to 6µm is deposited on the first coating layer (56a) by means of a PVD process in a fourth method step (68). The coated body comprises at least two coating layers (56a, 56b, 56c, 56d) with a thickness of 0.1µm to 6µm on a substrate (40), wherein an interface region formed by ion etching is arranged between the coating layers (56a, 56b, 56c, 56d).
