| 摘 要： | 采用自制的销盘式摩擦磨损试验机研究了三种颗粒增强铝基复合材料及灰铸铁(HT250)与半金属摩擦材料配副的干摩擦磨损性能。结果表明:在试验条件下,复合材料的耐磨性能高于灰铸铁(HT250),其中复合材料Al-10%Si/30%SiC(14μm)的平均磨损率小于灰铸铁的三分之一;复合材料的摩擦系数与HT250相当。而且从摩擦系数稳定性和摩擦系数达到最大值所需的时间来考察,复合材料的性能优于HT250。结果表明,颗粒增强铝基复合材料可以取代HT250,用于汽车刹车盘类摩阻件,使其使用寿命大幅度提高。 |

| Abstract: | The dry sliding tribological characteristics were investigated with self-made block-disk tester of SiC particle-reinforced aluminum composites and gray cast iron (HT250) against semi-metallic frictional materials. The experimental results indicate that the wear rates of SiC particle reinforced composites are much less (the wear rate of Al-10%Si/30%SiC(14μm) is about one third of that of gray cast iron) than that of gray cast iron which are commonly used to make brake disks, while the frictional coefficient is about the same. Based on the experimental results, the authors suggest that SiC particle-reinforced aluminum-matrix composite be one of the suitable materials for making vehicle-braking components. |
