Method for obtaining a configuration for joining a ceramic material to a metallic structure

Abstract

A configuration for joining a ceramic layer has a thermal insulating material to a metallic layer. The configuration includes an interface layer made of metallic material located between the ceramic layer and the metallic layer, which includes a plurality of interlocking elements on one of its sides, facing the ceramic layer, the ceramic layer comprising a plurality of cavities aimed at connecting with the corresponding interlocking elements of the interface layer. The configuration also includes a brazing layer by means of which the interface layer is joint to the metallic layer. The invention also refers to a method for obtaining such a configuration.

1 . A material for joining a ceramic layer comprising a thermal insulating material to a metallic layer, an interface layer made of metallic material located between the ceramic layer and the metallic layer, having a plurality of interlocking elements on one of its sides, facing the ceramic layer, the ceramic layer including a plurality of cavities aimed at connecting with the corresponding interlocking elements of the interface layer, and a brazing layer by means of which the interface layer is joint to the metallic layer. 
     
     
         2 . The material according to  claim 1 , wherein the plurality of cavities in the ceramic layer are filled with metallic filler, protruding from the ceramic layer, such that metallic struts are formed. 
     
     
         3 . The material according to  claim 2 , further comprising a defined gap between the ceramic layer together with the interface layer, with respect to the metallic layer, the cited gap being defined by selecting the length of the interlocking elements to define the metallic struts between the ceramic layer and the interface layer. 
     
     
         4 . The material according to  claim 1 , wherein the interface layer comprises a plurality of near wall cooling channels, the ceramic layer and the interface layer with the cooling channels being further brazed to the metallic layer.
