摘    要:研究了在Cu-Fe基烧结摩擦材料中SiO2和SiC对材料的力学性能特别是摩擦磨损性能的影响。结果表明 :添加SiO2摩擦材料的抗弯强度和摩擦因数分别为 141MPa和 0.277,添加SiC的分别为89MPa和0.255 ,添加SiO2+SiC的分别为109MPa和0.255。添加SiO2的摩擦材料磨损量为后两者的2倍 ,而添加SiC和SiO2+SiC的摩擦材料对对偶的磨损量比前者约大10倍。

Abstract: The effect of SiO2 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 SiO2 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.
