【Abstract】 The working mechanism of Fe in a new type of copper-based P/M friction material was studied.The results show that Fe works as frictional component in copper-based friction materials,influening the mechanical and frictional property of materials.Fe can increase the strength and hardness of friction material;when Fe is more than 4%,with the increase of Fe,the friction coefficient and stability of the material are enhanced.At the same time,at high speed friction,Fe takes part in formation of oxide film on friction surface,so the wear loss of friction material is decreased.更多还原
