A study has been made on the effect of shot peening on fretting fatigue, a complex deterioration phenomenon caused by the small amplitude relative motion of two metallic surfaces. To investigate this effect, two types peened specimens, having different surface roughness, and peened - annealed specimens were prepared. It was confirmed that shot peening improved fretting fatigue, and fretting fatigue strength increases with increasing roughness.
