/Al by powder pressed sintering method combined with stirring casting process.Micro-vickers hardness and as-cast microstructure of the novel aluminum-zinc composites were measured at different loading and time.The results reveal that the reinforced silicon carbide and graphite particles can be distributed uniformly in the matrix

and matrix hardness is increased by 8.5% with single adding SiC

while the matrix hardness is decreased by 15.4% with only adding GR

however

matrix hardness is reduced by 6.2% with adding SiC

.The temperature increment rate of the aluminum matrix zinc alloy reaches 45.7 ℃/s at 150 Nload

while the temperature increment rate of the composites with the single addition graphite particles is only 26.1 ℃/s

however

the temperature decrement rate reaches 50.4℃/s during the wear end stage.Meanwhile

the decrement rate of the composites with single addition silicon carbide particles is 33.6℃/s.At 30 Nfor 600s

anti-friction behavior of the composites with GR

p

exhibits desirable

and the wear loss of the matrix is reduced by 19%

while at 60 N for 600 s

the anti-friction and anti-wear effect of composites with the silicon carbide and graphite compound particles exhibits desirable

and the wear loss is reduced by 17%.In addition

the wear-resistance index of the composites with only adding SiC

p

is increased by 34% during wearing at 150 Nload.
