Additional information
Oxidation damage combined with fatigue is a concern for alloys used as disc rotors in aero-engines. Current alloys safely operate up to 600C, but forecasts suggest this temperature will rise, thus oxidation induced damage will become critical in disc lifing. This work, on oxidation induced sub-surface damage in the 700-800C range, has resulted in new contracts to assess oxidation and corrosion effects on the fatigue life of disc materials. Funding is provided by the TSB [TP11/CAT/6/I/BP009G] and directly by industry (contact mark.hardy@rolls-royce.com).
