Fretting fatigue studies were conducted on Ti-6Al-4V and 7075-T6 aluminum specimens cycled in axial fatigue loading at a fatigue ratio R of 0. 1. Fatigue loading was applied at 30 Hz in a laboratory environment with the fatigue specimen loaded in fatigue and fretting applied to the specimen central section through a fretting pad made of the same material as the specimen. Tests were conducted at various maximum loads and normal pressures.
