摘 要：The objective of present work is to apply the friction stir processing(FSP) to fabricate functionally graded Si C particulate reinforced Al6061 composite and investigate the effect of Si C particle mass fraction distribution on the mechanical properties and wear behavior of Al6061/Si C composite. Regarding the obtained results in this work, with increasing Si C mass fraction, elongation decreased, but hardness enhanced. However, the optimized functionally graded composite with the highest tensile strength and wear resistance was achieved for composite with 10 wt% surface Si C. Also,the results showed that wear resistance and tensile strength decreased for composite with 13 wt% surface Si C, due to reinforcement particle clustering depending on high Si C mass fraction.
