A novel approach to measure three-dimensional surface topography for stationary shoulder friction stir processing

We demonstrate a stationary shoulder friction stir processing (SSFSP) to produce smooth surface finish due to non-rotating action of the shoulder. The present work aims to investigate surface topography of high strength AA7075 aluminum alloy processed by SSFSP at different rotational speeds. The uni...
