The layer system comprises a substrate (4), and a ceramic layer (16) that is applied on a structured surface. The structured surface is formed by elongated recesses that form a honeycomb structure, and a stitch structure in quadratic or rectangular shape and have a breadth of 10-30 mu m and a depth of 10-30%. The ceramic layer has a thickness of 10-30 mu m. A distance of the opposite recesses is 100-300 mu m. The layer system further comprises an interfacial layer (10) such as a metallic layer made of chromium-aluminum (MCrAlX) alloy, where the interfacial layer is introduced into the recesses. An independent claim is included for a method for preparing a layer system.
