Abstract: A method according to disclosure may include removing only a portion of a used abradable material layer on a metal sealing surface of a first component that interacts with an abradable sealing element extending from a second component. The first and second component may be, in one example, vanes and rotor of a steam turbine, that sealingly move relative to one another in an operative state. The method includes thermal spray layer a new abradable material layer on the used abradable material layer, rather than completely removing the used abradable material and starting over on bare metal.

Abstract: A system for honing a shaft is provided. The system includes a rod having an axis and a head coupleable to the rod. The system also includes a drive motor coupleable to the rod such that the rod and the head are rotatable via the drive motor. The system further includes a linear actuator coupleable to the rod such that the rod and the head are translatable along the axis while being rotated via the drive motor.
