Abstract
An investigation was carried out to evaluate the feasibility of Friction Stir Powder Processing (FSPP) to produce particle reinforced Metal Matrix Composite materials. WC and TiB2 ceramic particles with particle sizes of 5 and 2 micron respectively were used as reinforcement particles. 2 mm depth surface layer of processed material were produced by multiple FSPP pass. The average hardness of the resulted composites increased to over 600 and 550 HV for steel/WC and Steel/TiB2 composite layer respectively. The fabricated steel/WC and Steel/TiB2 composite layer exhibited superior wear resistance
