Definitions

  • the invention relates to a layer system with a ceramic portion in the layer.
  • Layer systems consist of a substrate and at least one layer lying on the substrate.
  • substrates in gas turbine construction have to be protected against excessive temperatures and / or corrosive attacks. This can be done, for example, by applying a sheet with a honeycomb structure to the substrate, the honeycombs being filled with a ceramic.
  • the ceramic essentially takes on the protective function.
  • the sheet of the honeycomb structure serves to mechanically stabilize the ceramic.
  • the mechanical connection between the ceramic and the inner surfaces of the honeycomb structure is not good, so that the ceramic comes off again and again.
  • US Pat. No. 5,720,597 shows a blade for a gas turbine which at least partially has a foam-like area on the inside.
  • US Pat. No. 6,299,935 discloses a method for producing a layer, in which the surface of a substrate a suspension of foam and a metallic powder is applied.

  • the ceramic which is applied to the porous layer and at least partially introduced into it, can also form a mixture of different ceramic materials in order to set desired properties in a targeted manner.
  • the porous layer can be filled with ceramic, at least in some areas, in such a way that it is almost tight in these areas, so that an almost tight ceramic layer in the porous layer is achieved in order to take advantage of the advantages of ceramic in terms of heat resistance.
  • a further ceramic protective layer as is known, for example, from the thermal insulation layers of gas turbine blades, can be applied to the ceramic in the porous layer or above the porous layer in order to protect the ceramic in the porous layer from oxidation by means of a further coating.

  • the inner surfaces of the pores of the porous layer 4 are, for example, completely covered with a ceramic 16.
  • FIG. 3 shows a further exemplary embodiment of a layer system 20 designed according to the invention.
  • a porous layer 4 is applied to the substrate 1, the pores of which are filled with the ceramic 7, so that a dense layer is achieved.

Abstract

Les systèmes de couches de l'état de la technique, dans lesquels une couche céramique est appliquée sur une couche métallique du système de couches, se caractérisent souvent par une mauvaise liaison entre métal et céramique. Le système de couches (20) de l'invention présente une couche poreuse (4) dans laquelle se trouve au moins partiellement une céramique (7) de sorte que la liaison entre la céramique (7) et le métal de la couche poreuse (4) est de meilleure qualité.
