Abstract：Cu-based friction materials with different lubrication component such as the flake graphite, spherical
graphite, coke, artificial graphite, and cryptocrystalline graphite, were prepared by powder metallurgy technology.
The tribological and brake performance of Cu-based friction materials with different lubrication component were
tested by the MM3000 friction and wear tester. The results show that the average friction coefficient of the Cubased friction material with artificial graphite as lubrication component is the highest (> 0.40), but the wear loss is
the largest of all at the speed of 3 000~7 000 r/min. The friction coefficient of the Cu-based friction material with
coke is the second (> 0.375), and the wear loss is the smallest of all. The friction coefficient and wear loss of the
Cu-based friction material with coke is good than the Cu-based friction material with commonly used flake graph‐
ite. Under the braking condition of 7 000 r/min, the instantaneous friction coefficient of Cu-based friction material
with artificial graphite is the highest, and the braking time is short. However, the surface temperature rise of the Cu-based friction material with artificial graphite is the largest. The instantaneous friction coefficient and braking time
of the Cu-based friction material with coke is second, but the surface temperature rise of friction material is the
smallest. The overall performance of the Cu-based friction material with coke is better than the friction material
with flake graphite. Therefore, Cu-based friction materials with coke as lubrication component have better tribolog‐
ical and braking properties, relatively.
