HOT CORROSION OF GAS TURBINE ROTOR BLADE MATERIALS DUE TO A LONG TERM FIELD TESTING

As a result of 22,000 hr gas turbine engine operation burning residual oil fuels of high sulfur concentration, Inconel-700 blade has been severely affected owing to hot corrosion, whereas Inconel-X has been virtually free from such an attack. Consideration of the alloy composition suggests that molybdenum and cobalt in Inconel-700 and iron in Inconel-X are important elements in relation to hot corrosion. On the basis of metallographic, electron microprobe and X-ray diffraction analyses, the effect of the alloy composition in regard to hot corrosion mechanisms is discussed in some detail.
