Abstract
A method for the production of a sealing element with a backing 1 and a honeycomb structure 2 attached to this backing 1, in which the cellular arrangement of the honeycomb structure 2 is formed by individual, profiled layers 3 to 7 made of a thin, foil-like, metallic material, and in which the layers 3 to 7 are bonded to each other and the honeycomb structure 2 is bonded to the backing 1, wherein the bonding of the individual layers 3 to 7 of the honeycomb structure 2 and the bonding of the honeycomb structure 2 to the backing 1 is effected by means of a brazing process in which pure aluminum or an aluminum alloy is used as the brazing filler material.

A method for the production of a sealing element with a backing and a honeycomb structure attached to this backing, in which the cellular arrangement of the honeycomb structure is formed by individual, profiled layers made of a thin, foil-like, metallic material, and in which the layers are bonded to each other and the honeycomb structure is bonded to the backing, wherein the bonding of the individual layers of the honeycomb structure and the bonding of the honeycomb structure to the backing are performed by a brazing process in which pure aluminum is used as brazing filler material.
A method for the production of a sealing element with a backing and a honeycomb structure attached to this backing, in which the cellular arrangement of the honeycomb structure is formed by individual, profiled layers made of a thin, foil-like, metallic material, and in which the layers are bonded to each other and the honeycomb structure is bonded to the backing, wherein the bonding of the individual layers of the honeycomb structure and the bonding of the honeycomb structure with the backing are performed by a brazing process in which an aluminum alloy is used as brazing filler material, and wherein a subsequent heat treatment is performed at a temperature at least that of a temperature of the brazing.
A method for the production of a sealing element with a backing and a honeycomb structure attached to this backing, in which the cellular arrangement of the honeycomb structure is formed by individual, profiled layers made of a thin, foil-like, metallic material, and in which the layers are bonded to each other and the honeycomb structure is bonded to the backing, wherein the bonding of the individual layers of the honeycomb structure and the bonding of the honeycomb structure with the backing are performed by a brazing process in which an aluminum alloy is used as brazing filler material, wherein the brazing filler material is applied by bath aluminizing.
