Aluminium-based ceramics are widely used in aerospace, rail transit and national defense due to their advantages like light mass, high specific strength, small thermal expansion coefficient, high dimensional stability, high temperature resistance, remarkable fatigue resistance and excellent wear resistant. In this paper, SiCp-B4Cp(m(SiCp)∶m(B4Cp)=1∶1) reinforced Al matrix (i.e., (SiCp-B4Cp)/Al) composites were prepared by a selective laser melting (SLM) method with SiC and B4C as reinforcing phases and pure Al powder as a matrix material under certain conditions (i.e., powder layer thickness and hatch distance of 0.05 mm, scanning speed of 300 mm/s and laser power of 350 W). The effect of SiCp-B4Cp content on the microstructure, porosity, microhardness, friction and wear properties and flexural strength of (SiCp-B4Cp)/Al composites were investigated. The results show that the (SiCp-B4Cp)/Al composites reinforced with 10% SiCp-B4Cp exhibit the minimum apparent porosity (i.e., 4.5%) and flexural strength (i.e., 177 MPa), and the composites reinforced with 20% SiCp-B4Cp have the maximum hardness, lowest friction coefficient and wear rate (i.e., 172.6 HV0.1, 0.4 and 3.4×10-5 mm3N-1m-1).
