Abstract
The SiCp/6061Al composites with volume fractions of 10%, 20%, 30% and 40% were prepared by power metallurgy method. The effects of the volume fraction of SiCp on microstructure and mechanical properties were studied by means of phase analysis, microstructure observation, hardness test, friction test, wear and tensile test. The results show that the SiC particles distribute uniformly in the matrix and the interface bonding between the matrix and the reinforcement was exceptional. With the increase of the volume fracture of SiC particles, the distribution uniformity decreases, the hardness increases, the elongation decreases, with the tensile strength and wear resistance were increasing before slowly decrease. If the volume fracture of SiC particles is 30%, the comprehensive mechanical property is best that the hardness is 97.9 HV, the tensile strength 243 MPa, the elongation is 2.9% and wear rate is 1.21 × 10–5 g/m.
