Friction stir surface composites

Surface composites

The addition of reinforcement into the surface instead of bulk improves mechanical properties and boosts the surface properties of the composite. Friction stir processing (FSP) is a solid-state processing route for the fabrication of surface composite. Compared to the conventional liquid state processing route, the FSP is a compatible and energy-efficient process for fabricating surface composites. The FSP is a variant of the friction stir welding (FSW) process, carried out at a lower temperature than the base metal’s melting temperature.
