초록 ▼

Abradable seal composite structure having a porous, abradable ceramic surface layer which is resistant to high temperature oxidation and a metallic bottom layer capable of being bonded to a metallic substrate, with at least two intermediate layers consisting of ceramic/metal mixtures. The intermediate layer next to the ceramic layer has the highest ceramic content, with the remaining intermediate layers having progressively lower ceramic content and correspondingly higher metallic contents. The composite is made by laying up the layers in wet paste form and then drying them, after which the composite can be heated to bond it to the metallic substrate.

대표청구항 ▼

A multi-layer composite, sintered, abradable seal, which is resistant to thermal cycling and has a porous, abradable ceramic surface layer which is resistant to high temperature oxidation and a metallic bottom layer bonded to a metallic substrate, with at least two intermediate layers of ceramic/metal mixture, the relative proportions of ceramic and metal in each intermediate layer being gradated with respect to the other layers, with the highest percentage of ceramic in the intermediate layer adjacent to the ceramic surface layer and the composition in each succeeding layer being successively gradated to be lower in the proportion of ceramic with respect to the composition of the preceding layer. Process for producing a porous abradable seal on a turbine engine surface which comprises: a. forming a surface layer of desired thickness comprising particles of a ceramic material mixed with water and a binder to form a paste. b. forming an intermediate layer of desired thickness comprising particles of said ceramic material mixed with particles of a chromium-containing superalloy, water and a binder to form a paste, placing said layer on top of said surface layer. c. forming at least one additional intermediate layer as in step b, each such successive intermediate layer having a ratio of metal to ceramic gradated higher than that of the preceDing intermediate layer, and placing each such additional intermediate layer on top of the preceding intermediate layer. d. forming a metallic bottom layer of desired thickness comprising particles of a chromium-containing thickness comprising particles of a chromium-containing superalloy mixed with a brazing aid and water to form a paste, placing said metallic layer on top of the last intermediate layer. e. restraining the assembled layers in a suitable fixture under an initial pressure of at least 175 kilograms per square centimeter gauge and then slowly heating to dryness to thereby form a multi-layer composite. f. coating the surface of a metallic substrate fixture with a brazing powder comprising metal powder of the type used in step d plus a brazing aid. g. placing the dried composite on the coated metallic substrate, with the metallic bottom layer in contact with said substrate, and heating to a temperature of at least 1100°C in an inert or reducing atmosphere, under a pressure sufficient to maintain said composite in contact with said substrate for a time sufficient to sinter said composite and bond said composite to said substrate.
