ABSTRACT:
A machined-to-size superalloy turbine rotor disc for a gas turbine engine has its fatigue life increased by coating its fatigue-prone machined surfaces with an air-impervious protective layer of material which retains its integrity and adherence to the machined surfaces for a large number of mechanical and heat stress cycles.
