| Abstract: | Ceramic-enhanced Cu-based friction materials were fabricated by powder metallurgy. The friction and wear properties were measured by a friction tester under different pressures, friction speeds and wet/dry conditions. In the cases of dry friction, the friction coefficients are larger than 0. 3 and stable. As the friction pressure varies within 0.5 - 0.6 MPa, the fricition coefficient is lower, and the friction pressure has little effects on the wear rate. A maximum friction coefficient is found at the speed of 2 000 r/min. The materials exhibit lower friction coefficients under wet conditions than dry conditions. |
