Abstract:
In the current study， an effort has been taken to manufacture and compare the characteristics of functionally graded tubes. Two samples have been produced with a commercially pure aluminium matrix reinforced by 10%（in weight） SiC and Al2O3 with a 16 μm average size via horizontal centrifugal casting. In addition to microstructure analysis， the mechanical and wear characteristics have been investigated across the thickness of the produced tubes. The results showed that the addition of SiC and Al2O3 particles relative to the unreinforced matrix （pure Al） significantly enhance the mechanical properties and wear resistance of the produced tubes. Thus， these tubes are the best choice for automobile applications.
