Article Preview

The Cu-based friction materials with nano-AlN (n-AlN) and nano-graphite (n-C) were prepared by powder metallurgy technology, respectively. The microstructures and friction performance were studied through scanning electron microscope (SEM) and friction tester rig, respectively. The results indicate that the n-AlN and n-C particles can enhance the properties of Cu-based friction materials remarkably. Compared with the friction materials without any nanometer materials, the wear resistance of the friction materials with n-AlN and n-C has been improved by 25 % and 11 %, respectively. The heat resistance of the materials with n-AlN and n-C has been improved 18 % and 25 %, respectively. The n-AlN and n-C particles can reduce the abrasive wear and enhance the wear resistance of the Cu-based friction materials.
