摘要：
The composite electroforming technology was used to fabricate nanosized alumina particles (nano Al2O3) reinforced copper matrix composite. The surface, fracture and wear surface morphology were observed by scanning electron microscopy (SEM) as well as microstructure observed by transmission electron microscopy (TEM). Microhardness, tensile properties, wear resistance and electrical resistivity Er were investigated. The results showed that Cu/nano Al2O3 composites with different compositions were obtained successfully by composite electroforming technology. Nano Al2O3 particles were dispersed in copper matrix uniformly and tightly. By comparing with the electroformed pure copper, Cu/nano Al2O3 composites achieved higher microhardness, better mechanical property and wear resistance, and just a little effect of nano Al2O3 on the electrical property of composite was presented.
