Effect of Nano-AlN on the Friction Performance of Cu-Based Friction Material

Abstract:

Article Preview

The Cu-based friction materials with nano-AlN (n-AlN) particles were prepared by powder metallurgy technology. The friction performance of the friction materials was investigated through test rig. The microstructure and worn morphology were studied through scanning electron microscopy (SEM). The results indicate that the coefficient of the Cu-based friction materials with 0.75 wt % n-AlN is high and stable. Comparing with the traditional friction materials without n-AlN, the wear resistance and heat resistance of the friction materials with n-AlN has been improved by 25 % and 18 %, respectively. The n-AlN particles can reduced the abrasive wear and enhance the wear resistance of the Cu-based friction materials.
