Combustor member and method for making a combustor assembly

A turbine engine combustor member (14/18/26/38/52), for example a deflector (52) including an inner surface (40) at a combustor interior (11) and an outer surface (41) away from such interior (11) includes a body (42) of a high temperature alloy having properties combining resistance to hot corrosio...

Zusammenfassung:	A turbine engine combustor member (14/18/26/38/52), for example a deflector (52) including an inner surface (40) at a combustor interior (11) and an outer surface (41) away from such interior (11) includes a body (42) of a high temperature alloy having properties combining resistance to hot corrosion and oxidation to avoid coating the outer surface (41). In one embodiment (52), the inner surface (40) includes an environmental resistant coating (53) comprising a ceramic-base thermal barrier coating (56). In some forms such coating (53) includes an inner coating (54) including Al under the ceramic-base coating (56). In another embodiment, the member (26) includes air cooling passages (48) and is substantially uncoated. Provision of such a member (14/18/26/38/52) enables complete combustor (10) assembly including a plurality of members (14/18/26/38/52) and then coating all inner surfaces (17/40) concurrently rather than individually before assembly.
