LAYERED ARRANGEMENT, HOT-GAS PATH COMPONENT, AND PROCESS OF PRODUCING A LAYERED ARRANGEMENT

摘要

A layered arrangement, a hot-gas path component, and a process of producing a layered arrangement are disclosed. The layered arrangement includes a substrate layer, a ceramic matrix composite layer, and a non-metal spacer between the substrate layer and the ceramic matrix composite layer configured to define one or more pockets. The hot-gas-path component includes a nickel-based superalloy layer, a ceramic matrix composite layer, and a ceramic spacer between the nickel-based superalloy layer and the ceramic matrix composite layer. The ceramic spacer is mechanically secured to one or both of the substrate layer and the ceramic matrix composite layer, and the ceramic spacer is bonded to the substrate layer or the ceramic matrix composite layer. The process includes securing a non-metal spacer between a substrate layer and a ceramic matrix composite layer of the layered arrangement.

1. A layered arrangement, comprising:
a substrate layer; a ceramic matrix composite layer; and a nonmetal spacer between the substrate layer and the ceramic matrix composite layer configured to define a plurality of pockets, wherein the plurality of sockets contain a substance including a property of greater thermal insulation than the substrate layer, and wherein the substrate layer. the ceramic matrix composite layer and the non-metal spacer are configured to enclose the plurality pockets, isolating each of the plurality of pockets from one another.
