| 摘 要： | 采用SPS方法制备出SiC和Ti3SiC2双相增强Al基复合材料,并在MM-200型摩擦磨损实验机上进行干摩擦试验。研究了不同含量SiC对Ti3SiC2/Al复合材料组织及耐磨性的影响,结果表明,颗粒体积分数及磨损载荷对复合材料摩擦磨损特性有显著影响。复合材料具有良好的摩擦磨损性能,烧结温度为550℃,SiC的体积分数从0.5%上升到2%时,复合材料的摩擦系数从0.34降到0.285,降低16.2%。烧结温度为400℃,SiC的体积分数从0.5%上升到2%时,复合材料的磨损量从0.0079降到0.0039,降低50.63%。

| Abstract: | SiC and Ti3 SiC2 dual-phase-reinforced Al-based composites are fabricated with spark plasma sintering technique, then dry friction test is carried out on MM-200 tribological machine to study the effects of the content of SiC on structure and tribological properties of TiaSiC2/Al composites. The results show that both the volume fraction and abrasion load influence the tribological properties of the composites, and the composites have good tribological properties, at temperature 550 ℃, the volume fraction of SiC increases from 0.5 G to 2%, the friction coefficient of composites drop from 0.34 to 0. 285（decrease 16.2%）, while at temperature 400 ℃ the volume fraction increase from 0.5G to 2% and wear extent drops from 0. 007 9 to 0. 003 9（decrease 50. 63%）. |
