Surface composites

Friction stir processing (FSP) is a suitable solid state processing route for surface composite preparation. Solid state processing route is superior in terms of compatibility and energy efficiency compared to conventional liquid state processing methods. The FSP, derived from the friction stir welding (FSW) process, is carried out at temperatures lower than the melting temperature of the base alloy. The surface composite preparation through FSP imparts minimal thermal effect on the processed material. Aluminium surface composites by FSP exhibit improved surface properties retaining the structural properties of the Al base alloy. Our research work is on the preparation and characterization of Aluminium metal matrix surface composites through friction stir processing. The correlation between the process parameters and surface property enhancement is the major objective of this research work.
