采用粉末冶金技术制备了以SiC为磨料的Cu-Fe基连续制动摩擦材料，研究了SiC含量和粒度对材料性能的影响。在环块摩擦磨损试验机上研究了不同载荷和滑动速度下摩擦材料与AISI 1045钢环副摩擦副的摩擦学性能。纳米SiC（55 nm）对摩擦材料摩擦学性能的强化效果上级优于微米SiC（70 μ m）。摩擦材料的摩擦系数随纳米SiC含量的增加而增大。随着纳米SiC含量的增加，磨损率逐渐降低，当纳米SiC含量超过10wt%时，磨损率又逐渐升高。在不同的试验条件下，纳米SiC含量为10%的试样具有最佳的摩擦学性能。
The Cu-Fe matrix continuous braking friction materials using SiC as abrasive were fabricated by powder metallurgy technique, and the effect of content and size of SiC were investigated. The tribological properties of friction materials sliding against AISI 1045 steel ring were carried out on a block-on-ring tester at different loads and sliding speeds. The strengthening effect of nano-SiC (55 nm) was superior to that of micro-SiC (70 mu m) of the tribological properties for friction materials. The friction coefficients of friction materials increased with increasing nano-SiC content. However, the wear rates decreased with increasing nano-SiC content and then increased when the content of nano-SiC particle exceeded 10 wt%. The specimen contained 10% nano-SiC had the best tribological properties at different testing conditions.
