【Abstract】 The effect of iron concentration on the physical and mechanical properties as well as friction and wear characteristics of Cu Fe based P/M friction materials has been studied.The results show that the hardness, compressive strength and bending strength of the material gradually increased with the increase of iron concentration (Cu concentration decreased relatively ) when all other compositions as well as their concentrations were kept constant. It has also been found that the material containing 20% Fe possesses excellent comprehensive properties such as high and stable coefficient of friction ( μ ) and moderate wear rate.更多还原
