Coating system with a porous layer

摘要

Layer system (20) comprises: a substrate (1); an outer porous layer (4) having a pore volume of at least 30 vol.% arranged on the substrate; and a ceramic (7) partially arranged in the porous layer. Preferred Features: The porous layer has an open pore structure. The ceramic is a mixture of various ceramic materials. The porous layer is partially filled with the ceramic. The porous layer is a foam-like material or a metal. The substrate is made from a cobalt/nickel super alloy.
