Abstract: Aluminium alloy 6061(AA6061) matrix composites reinforced with nano-SiC particles were produced. The microstructure, Vickers microhardness and characteristic wear properties of the composites were investigated. The results showed that the wear rate and the friction coefficient values of the composites are lower than the matrix alloy at 20 N load, the wear rate of 0.6%SiC/AA6061 decreases 50% than the matrix. This is attributed to the strong bonding between the matrix and the particles in the composites. So the presence of SiC particles in the composites improves the wear resistance because these particles remain intact and retain their load-bearing capacity, they promote the formation of iron-rich transfer layer. The dominant wear mechanisms are found to be abrasion for the AA6061 alloy and its composites at 20 N load.
