Abstract
The invention relates to an erosion protection coating (), in particular, for gas turbine components, having a horizontally segmented and/or multi-layered construction. i.e., having at least one relatively hard layer () and having at least one relatively soft layer (), wherein the relatively hard layer or each relatively hard layer as well as the relatively soft layer or each relatively soft layer are disposed on top of one another in an alternating manner, in such a way that an outer-lying layer, which forms an outer surface of the erosion protection coating, is formed as a relatively hard layer (). According to the invention, the relatively hard layer or each relatively hard layer () as well as the relatively soft layer or each relatively soft layer () are formed as a ceramic layer in each case.
