The effects of SiC particles under different sintering temperature on microstructures and properties of 10% (volume fraction) SiCp/ZL109Al composites were investigated in this paper. After 5 hours oxidation sintering, SiC particles were added into molten aluminum. By use of stirring casting method, an aluminum matrix composite was prepared. The thickness of SiC oxidation layer increased with increasing the sintering temperature from 800℃ to 1100℃. TEM observation revealed that the oxidation layer formed in 900℃. When temperature increased higher than 1000℃, SiC Particles are completely covered by oxidized layer. The thickness of oxidation layer was 0.096-0.5425um with sintering temperature from 800℃ to 1000℃. The density and friction coefficient of composite would be the best under the condition of sintering temperature was 1000℃. At that time the oxidation layer was 0.383um and MgAl2O4 phase generated instead of Al4C3 on the layer which would enhance combination strength of composite with stronger matrix interface.
