Abstract (en)
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.
Abstract (de)
Durch die Einbringung von Vertiefungen (19', 19'', ...) in eine Oberfläche (7, 13) werden die Spannungen in der keramischen Schicht (16) an den metallischen Untergrund reduziert, so dass eine längere Lebensdauer für die keramische Schicht erzielt wird.
