Abstract:
1. A wear-resistant coating having an alternating layered structure comprising a plurality of relatively hard ceramic layers and a plurality of relatively soft metallic layers, wherein the ceramic layers and the metallic layers are alternatingly positioned on top of one another such that an external layer, which forms an outer surface of the wear-resistant coating, is designed as a ceramic layer, wherein the external ceramic layer and a ceramic layer nearest the external layer are vertically segmented in the manner of a column such that each of the external ceramic layer and the ceramic layer nearest the external layer comprise layer columns, the layer columns extending through the layer in which the layer columns are located, the layer columns extending approximately perpendicular to a surface of a gas turbine component to which the wear-resistant coating is applied, wherein a metallic interlayer is interposed between the external ceramic layer and the ceramic layer nearest the external layer, and wherein said coating is used as a coating for gas turbine components.
