Abstract
A novel surface modifying technique, Friction Stir Processing, is used to
enhance mechanical properties of Al-Si / Al2O3 composite, through micro
structural refinement and homogenization. The effect of processing parameters on
resultant microstructure and wear rate is investigated in this work.
The Friction Stir Processing resulted in significant breakup of the coarse Si
and Al-dendrites and uniform distribution of Si and Al2O3 in the matrix with
significant micro structural refinement. These microstructures changes lead to
significant improvement in wear resistance of composite
