Hybrid ceramic material composed of insulating and structural ceramic layers
TLDR
In this paper, a hybrid ceramic structure is proposed for high temperature environments such as in gas turbines, which is made from an insulating layer of porous ceramic that is thermally stable at temperatures up to 1700 C bonded to a high mechanical strength structural layer of denser ceramic, where optional high temperature resistant adhesive can bond the layers together.Abstract:
A hybrid ceramic structure (10), for use in high temperature environments such as in gas turbines, is made from an insulating layer (12) of porous ceramic that is thermally stable at temperatures up to 1700 C bonded to a high mechanical strength structural layer (8) of denser ceramic that is thermally stable at temperatures up to 1200 C, where optional high temperature resistant adhesive (9) can bond the layers together, where optional cooling ducts (11) can be present in the structural layer and where hot gas (14) can contact the insulating layer (12) and cold gas (15) can contact the structural layer (8).read more
