Zusammenfassung:In the presented method for the manufacture of a thermal barrier coating structure (2) on a substrate surface (3) a ceramic coating material is applied onto the substrate surface by means of plasma spraying, wherein the thermal barrier coating structure includes at least two differently produced thermal barrier coatings (2.1, 2.2). For the manufacture of the one thermal barrier coating (2.1), the coating material is sprayed onto the substrate surface in the form of a powder jet by plasma spraying at atmospheric pressure (atmospheric plasma spraying or in abbreviation APS), and for the manufacture of the other thermal barrier coating (2.2) the coating material is applied onto the substrate surface by means of plasma spraying-physical vapor deposition or in abbreviation PS-PVD, such that a layer having elongate corpuscles develops on the substrate surface, which corpuscles form an anisotropic microstructure and are aligned essentially perpendicular to the substrate surface.
