Friction Stir processing

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.

Friction stir channeling

The Friction stir channelling (FSC) process is based on the concept of transforming the void or tunnel defect originating in advancing side of Friction Stir process into continuous integral channel. The process was first invented and patented as manufacturing technique for heat exchanging devices and can have wide range application in compact heat exchanger industries. The important aspect for use of the channel in any thermal application is thermo-hydraulic performance. The geometrical parameters of channel (Shape, Cross Sectional Area, Surface Area, hydraulic diameter, Surface Roughness, and Length) decide the thermo-hydraulic performance of channel.
