Abstract
A seal assembly for use in a turbomachine is provided. The seal assembly has an annular division wall with outside and inside surfaces, a carrier ring disposed adjacent the inside surface of the annular division wall, and a sealing substrate metallurgically-bonded to an inner-most surface of the carrier ring. The sealing substrate is machined to form a seal surface that can be disposed proximate a rotor and maintained substantially parallel thereto during operation of the turbomachine.
