註釋Friction dampers are required to reduce the magnitude of vibrational stresses in high-aspect-ratio blading of compressors for advanced aircraft turbine engines. Fret ting Is a common problem with all types of friction dampers. Fretting experiments with simulated wire-lace blade damping were conducted with Inconel 600. Experiments were run with or without oxide coatings In contact with maraging steel. Although two methods were used to form the oxide, high friction and low wear occurred with both. Further wear experimentation with oxidized material rubbing against itself showed that friction and wear were decreased by operation at a higher temperature (500 deg F or 260 deg C).
