The role of surface integrity in obtaining long time reliability during fatigue cycling is well known; hence, manufacturers of large complicated rotating apparatus such as steam turbines are aware of the need to select adequately fine surface finishes for all components subjected to vibratory loading. Particularly important areas to obtain turbine reliability under fatigue cycling occur at the rotating blades and rotor-blade fastenings. Failure of either will result in a forced outage of the entire turbine-generator set and a subsequent major disassembly operation. The diagram in Figure 1 should give the reader some idea of what this disassembly entails.
