Research on Tribological Properties of Nano-SiO2/Cu Composites

摘要：

　　Cu-based nanometer composites with ω (n-SiO2) =1.0 % nano-SiO2 were prepared through ball milling and powder metallurgy technology.The friction and wear performance of the composites was investigated by ball-disk friction and wear tester.The microstructure and wear morphology were studied by drainage and field scanning electronic microscope (FSEM),respectively.The results indicate that ball milling can improve the spatial distribution ofnano-SiO2 in the copper matrix.With the ball milling time increasing,the dynamic friction coefficient and wear rate of the composites decrease firstly and then increase.The composite milled 10 h has the lower friction coefficient and wear rate,and its main mechanism is abrasive wear.
