SiCp/ZL101A composites were prepared by hot-presses sintering process（HPS） with SiC particles of 10%

20%

30% and 40% in volume fraction.The hardness and dry frictional wear behavior at room temperature were measured

and the wear mechanism was approached.The results show that

with increasing in volume fraction of SiC particles

hardness of the composites is increased

and the maximum hardness value can be observed in the composites with 30% SiC content.The wear mechanism of the matrix ZL101A alloy is characterized by adhesion wear

while wear mechanism of the composites is characterized by adhesion wear with a little abrasive wear.With increasing in volume fraction of SiC particle

the adhesion wear is gradually reduced

which is responsible for the improvement of wear behavior of the composites.
