Abstract
Official abstract text for this publication.
A process for rejuvenating a turbine disk having a plurality of slots includes the steps of determining a depth of a damaged layer containing M23C6 carbide dissolution; and removing the damaged layer from the slots in accordance with the determined depth.
First claim
Opening claim text (preview).
What is claimed is: 1. A process for rejuvenating a turbine disk having a plurality of slots comprising: determining a depth of a damaged layer containing M23C6 carbide dissolution; re-machining said slots to remove said damaged layer from said slots in accordance with the determined depth; and installing new blades/buckets into said re-machined slots having a size larger than a size of removed blades/buckets. 2. The process of claim 1 , wherein said determining step comprises creating a model showing the depth of M23C6 carbide dissolution vs. time and temperature. 3. The process of claim 1 , further comprising removing blades/buckets having an original size from said slots. 4. The process of claim 1 , wherein said re-machining comprises using one of super abrasive machining, wire EDM, broaching, grinding, and milling. 5. The process of claim 1 , wherein said re-machining step further comprises re-machining other high temperature exposed surfaces.
