Al-Cu-Mg alloy and its matrix composites reinforced with different volume fractions of sub-micron silicon carbide particles have been produced in powder metallurgy route. The effects of silicon carbon particles and mechanical alloying (MA) technology on the mechanical and tribological properties were investigated. The results show that the composites have better mechanical and tribological properties than the matrix alloy, and the 9vol%SiCp/Al-Cu-Mg composite has the best performances. Mechanical alloying (MA) technology further improves the hardness and tensile strength, hardly influences the wear rate of the 9vol%SiCp/Al-Cu-Mg composite but somewhat affects its friction coefficient.

The SiC/Cu composite is one of the "structural-functional" materials. It shows good mechanical properties and very high thermal, high electrical conductivity etc. But the co-dispersion, wetting and bonding between SiC and Cu interface are of practical importance in the preparation of SiC/Cu composites. In this work, surface treatment techniques such as high-temperature oxidation, acid dipping and alkaline wash were adopted separately on silicon carbide particles, in order to improve the wettability and physical and chemical compatibility between silicon carbide and copper, then we used the replacement reaction method and decomposition-reduction reaction method to generate Cu coating on the surface of silicon carbide. The results shown that, the surface of silicon carbide particle which treated by alkaline wash was cleaner and more rough than that only treated by high-temperture oxidation, moreover, the specific surface of the particle was increased, which resulted in a compact layer of Cu coating. for the same silicon carbide particles, the effect of the Cu coating prepared by decomposition reaction method was better than that by reduction reaction method.
