In this study, the wear behaviors of the solution-treated and as-extruded SiCp/AZ91D metal matrix composites with differentsizes and volume fractions of SiC particles were systematically investigated under different wear test parameters. The SiCparticles exhibited a typical necklace-type distribution in the solution-treated composites and a homogeneous distributionin the as-extruded composites. Wear tests results showed that the wear rates of the as-extruded composites were lower thanthat of the solution-treated composites almost under all testing conditions and with the same SiC size and volume fraction. However, the dominant wear mechanisms for these two types of composites were different. The typical necklace-type distributionof SiCpin the solution-treated composites could effectively promote the occurrence of delamination owing to theweak bonding between SiCpand matrix in the particle aggregated regions. By contrast, as the bond between disperse SiCpand matrix was enhanced, the homogeneous distribution of SiCpin the as-extruded composites could promote the occurrenceof adhesion and prevent the occurrence of delamination. Moreover, a higher applied load and higher volume fraction of SiCpobviously promoted the progress of delamination for the solution-treated composites, while the extent of the adhesive wear forthe as-extruded composites was mainly associated with the increase of the applied load, sliding velocity and SiC particle size.
