Abstract

A thermal barrier system includes a protective coating on a substrate, and a ceramic feature layer attached to the protective coating via an adhesive spray coat.

Claims

exact text as granted — not AI-modified
1 - 14 . (canceled) 
     
     
         15 . A method of applying a thermal barrier system to a component, comprising:
 applying a protective coating to a substrate; and   mechanically interlocking a ceramic feature layer with the protective coating via an adhesive spray coat thermally sprayed onto the ceramic feature layer and the protective coating that partially fills said ceramic feature layer such that said ceramic feature layer at least partially extends from said adhesive spray coat.   
     
     
         16 . The method as recited in  claim 15 , wherein the ceramic feature layer is mechanically attached to the protective coating prior to thermally spraying the adhesive spray coat. 
     
     
         17 . The method as recited in  claim 15 , wherein the ceramic feature layer is temporarily tacked to the protective coating prior to thermally spraying the adhesive spray coat. 
     
     
         18 . The method as recited in  claim 15 , further comprising preforming the ceramic feature layer. 
     
     
         19 . The method as recited in  claim 15 , further comprising additively manufacturing the ceramic feature layer. 
     
     
         20 . The method as recited in  claim 15 , further comprising at least partially filling the ceramic feature layer with the adhesive spray coat.
