Shot peening to reduce stress corrosion

As can be seen from the work carried out by Seong Kyun cheongl, Ji Hun am’, Jae Heon ~ee’, Tae Hyung ~im~ Seoul National University of Technology, Nowon-Gu, Seoul 139-743, Korea ‘ he Graduate School of Energy & Environment, Seoul National University of Technology, Nowon-Gu, Seoul 139-743, Korea Department of Mechanical Engineering, Sogang University, Mapo-Gu, Seoul 121-742, Korea from their paper entitled ‘EFFECTS OF SHOT PEENING ON THE CORROSION FATIGUE LIFE OF AL 7075-T6’. The following data is extracted from that work identifying the significance of shot peening on the resistance to corrosion and hence the improvement in fatigue life.
