Abstract
A copper matrix friction material of multi-element is prepared using powder metallurgy process,and GF150 D type friction tester is used to analyze and compare the comprehensive friction and wear performance of the material in different friction conditions. The results show that the friction coefficient is decreased and wear is increased with incresing friction pressure in inertia friction condition. The friction coefficient at fixed speed is bigger than that in inertia friction when all other friction conditions are the same. In the inertia friction experiment,the wet friction coefficient is significantly higher than that of dry one. The stability of the friction coefficient in the sequence of high to low speed is higher than that in the sequence of low to high speed.
