Surface roughness and friction coefficient in peened friction stir welded 2195 aluminum alloy

The tribological properties of friction stir welded 2195 aluminum alloy joints were investigated for several laser- and shot-peened specimens. The first portion of this study assessed the surface roughness changes at different regions of the weld resulting from the various peening processes and incl...
