摘要： A composite face seal having an annular seal rotor with a metal base portion and a radially extending flange. The flange having first and second axially facing surfaces. A first ceramic ring is mounted to the first surface of the flange by a first braze joint and a second ceramic ring is mounted to the second surface of the flange by a second braze joint. The composite face seal assembly further includes an annular stator having an axially facing surface that sealingly engages an axially facing surface of one of the ceramic rings. Each of the braze joints may comprise a molybdenum ring disposed between two braze rings or, for thicker seal assemblies, molybdenum and nickel rings disposed between braze rings.
