Abstract

A two-layered NiCoCrAlY layer is provided. The layer includes a bottom and a top layer. Through the use of a two-layered NiCoCrAlY layer, it is possible to reduce the formation of cracks in the thermally grown oxide layer as forms on account of the protective action of the NiCoCrAlY layers.
