Summary

Surface treatment by shot-peening (SP) has been known for many years as an established process for increasing the fatigue life of steels and non-ferrous alloys [1, 2]. The impact of the shot media on the surface leads to plastic deformation and compressive residual stresses in the surface layer, obstructing the nucleation and propagation of fatigue cracks in or near the surface [3-5].

The aim of the present study is to apply the latter method and investigate the fatigue and corrosive behavior after secondary peening with glass beads.
