Friction Stir Surfacing of Copper
Malkeshwar Vinod Kumar | Dr. S. V. Satish 
Abstract: The main objectives of the present investigations includes optimization of Friction Stir surfacing process parameters which include selection of appropriate rotational speed, traverse speed, axial force and evaluation of wear properties between parent material and deformed material. The experiment includes the study of surface wear features of severely deformed surface formed by friction stir mechanism. In the present experiment there is no addition of extra coating of material but instead the surface is deformed under huge compressive load using friction stir welding equipment. The process incorporates a hot forging action, which refines the microstructure of the surface material significantly, thus improving its basic surface properties. Friction stir surfacing can be considered as an alternative work for fusion based overlay coatings. The process applications are for corrosion and wear resistant coatings and for reclamation of worn out components.
