Abstract
The invention describes a temperature-stable protective coating over a metallic substrate surface ( ), which coating includes at least one layer of material ( ) consisting of MCrAlY, where M represents at least one of the elements selected from the group of materials consisting of Fe, Co and Ni. The invention also describes a production process for this coating. The invention is distinguished by the fact that a multiplicity of local elevations, known as rivets ( ), are provided distributed directly over the area of the substrate surface ( ) or distributed indirectly over the area of the substrate surface, separated from the substrate surface ( ) by means of at least one interlayer ( ), which rivets are fixedly joined to the substrate surface ( ) or the interlayer ( ), that at least one layer of material ( ) consisting of MCrAlY is deposited on the substrate surface ( ) or interlayer ( ) in such a manner that the layer of material ( ) consisting of MCrAlY completely surrounds the rivets ( ), completely fills regions which lie between adjacent rivets ( ) and projects above the rivets ( ).
