Abstract
Copper-based friction materials with different oil groove depth and graphite content were prepared by powder metallurgy process. The effect of oil groove depth on the friction performance of copper based friction materials with different graphite content at different linear velocities was studied. The results show that the dynamic friction coefficient of material decreases with the increase of oil groove depth at low linear velocity of 16.5m/s, and increases with the increase of oil groove depth when linear velocity is ≥ 20m / s. With the increase of oil groove depth and graphite content, the heat resistance of the friction material increases and the wear rate decreases.
