Abstract: The present disclosure includes a method of forming a polished surface. Forming the polished surface can include grinding an initial ceramic substrate to form a ground ceramic substrate; infiltrating the ground ceramic substrate with silicon; and polishing the silicon-infiltrated ceramic substrate, thereby forming the polished surface.

Abstract: Technologies are described herein for a seal assembly for an engine, the seal having a circular carbon graphite mating surface and a circular carrier mating surface. A planar face of the circular carrier mating surface includes a circular bevel, which may be configured to receive a removable ringed insert. When inserted into the circular bevel, the ringed insert mates with a planar face of the circular carbon graphite mating surface. The carbon graphite mating surface, the circular carrier mating surface, and the circular of the carrier mating surface are aligned to have a common central axis along an engine shaft.
