In order to investigate the effects of surface polishing for high cycle fatigue property on the laser peened Ti-6Al-4V specimen, the rotating bending fatigue test were carried out with three kinds of the electrical polished(EP) specimen, mechanical polished(MP) specimen and MEP specimen was polished with both polishing. As the results, the fatigue limits of polished specimens were not improved and the fracture surfaces showed characteristic appearance.
