Abstract

A process for producing a spatially shaped carrier layer ( 3 ) which is of foil-like design from hard brittle material includes: providing a basic mold ( 1 ) having a spatially shaped surface, depositing a material which is in the gas or liquid phase on the spatially shaped surface, solidifying the material which has been deposited on the spatially shaped surface to form a hard brittle material layer ( 3 ), and separating the hard brittle material layer ( 3 ) from the spatially shaped surface in order to obtain the carrier layer ( 3 ) which consists of hard brittle material.

Claims (12)

1. A process for producing a spatially shaped carrier layer from hard brittle material, comprising:

providing a basic mold having a spatially shaped surface;

depositing a material which is in the gas or liquid phase on the spatially shaped surface;

solidifying the material which has been deposited on the spatially shaped surface to form a hard brittle material layer; and

separating the hard brittle material layer from the spatially shaped surface to obtain the carrier layer of hard brittle material;

wherein depositing the material comprises depositing liquid phase material on the surface of the basic mold by melt spinning, wherein the basic mold comprises a rotating structured roller, and comprising applying the liquefied material to a cooled surface of the structured roller through a discharge nozzle in the form of a widened let sheet of material, the liquefied material cooling and solidifying and being peeled off the structured roller as a result of the rotation of the structured roller in the form of a solidified, structured carrier layer.

2. The process as claimed in claim 1 , wherein the hard brittle material comprises MCrA1Y.

3. The process as claimed in claim 1 , wherein the spatially shaped surface has a multiplicity of spatially periodically recurring elevations and/or depressions which are of identical design.

4. The process as claimed in claim 3 , wherein the elevations or depressions are in each case in the form of a half of a honeycomb structure.

5. The process as claimed in claim 1 , wherein at least two carrier layers, which comprises hard brittle material, are joined to one another as a sheet to form a three-dimensional structure comprising hard brittle material.

6. The process as claimed in claim 5 , wherein at least two carrier layers, which comprise hard brittle material and are in each case in the form of halves of a honeycomb structure, are joined together to form a spatial honeycomb structure.

7. The process as claimed in claim 5 , wherein joining of the at least two carrier layers comprises soldering or welding.
