摘要: 

通过挤压铸造的方法制备出了不同Cu含量的系列Al2O3·SiO2sf/Al-Cu复合材料. 摩擦磨损实验结果表明,Cu的加入降低了复合材料的摩擦系数; 且随着Cu含量的增加, Al2O3•SiO2sf/Al-Cu复合材料的耐磨性能先增加后降低. 在磨损过程中, Al2O3•SiO2纤维增强相牢固地镶嵌在基体里并形成支架, 起到保护基体而提高复合材料耐磨性能的作用. Al2O3•SiO2sf/Al复合材料的磨损机制主要为黏着磨损,Al2O3•SiO2sf/Al-Cu复合材料的磨损机制为黏着磨损为主并伴有磨粒磨损.

Abstract

Al2O3•SiO2sf/Al-Cu composites with different Cu contents were successfully fabricated by squeeze casting. The wear test results show that friction coefficient of the composites decreases with increasing Cu contents. Moreover, the wear resisting property of the prepared composites firstly increases and then decreases with increasing Cu contents. In wear testing process, Al2O3•SiO2 fibers are firmly fixed in the matrix and formed the framework which can protect Al matrix from grinding. Therefore, the wear resistance of the composites is increased by addition of Al2O3•SiO2 fiber reinforcement. The main wear mechanism of Al2O3•SiO2sf/pure Al composite is adherence abrasion, while that of Al2O3•SiO2sf/Al-Cu composite is adhesive wear accompanied by abrasive wear.
