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.
The friction stir channel (FSC) extends the friction stir process where an integral channel is fabricated by continuous voids or tunnel defects. FSC can generate the subsurface path in complex shapes as the processing is performed from the workpiece surface. The unique features of the process can fulfil the advanced heat sink applications in critical thermal management systems such as cooling of EV battery cells, data servers, jet engines and aircraft components.
