【Abstract】 The effects of SiO₂, SiC and B₄C on physical and mechanical properties, especially friction and wear characteristics of Cu-Fe matrix sintered friction materials have been studied. The results show that using SiO₂, SiC, B₄C together as friction modifiers of materials is much better than using SiO₂, SiC respectively or SiO₂, SiC together. The material which contains SiO₂, SiC and B₄C together as friction modifies prosesses excellent synthetic properties.更多还原
