| Abstract: | The effect of SiO 2 and SiC on the physical and mechanical properties, especially friction and wear characteristics of Cu Fe based sintering friction materials has been studied. The results show that bending strength of the materials which contains SiO 2 reaches 141?MPa, and only 89?MPa for the material which contains SiC. The friction coefficient of the former is higher than that of the latter, but its wear amount is twice as high as that of the latter. The wear amount of its matching material is very low. Adversely, the wear amount of the matching material of the material which contains SiC is rather high. |
