Effect of Shot Peening on the Strength and Corrosion Properties of 6082-T651 Aluminium Alloy

This paper investigated the effect of shot peening on strength and corrosion properties 6082-T651 aluminium alloy. The microstructure, surface roughness, microhardness, residual stresses, behaviour were compared with those untreated Cracks delaminations in layer could only be seen treated specimens at a working pressure 4 bar 8 bar, while no such was observed 1.6 bar. roughness increased more than 15 times after Shot resulted an increase microhardness 27% deeper higher compressive stresses to specimens. All exhibited improved resistance lower degree anodic dissolution. current density specimen lowest two-fold that specimen.
