摘要

航空航天和汽车工业对铝基金属基复合材料的需求正在增长，因为它具有良好的耐腐蚀性和高强度重量比。研究了以AA6063、碳化硼和硅酸锆为原料合成的搅拌铸造复合材料的摩擦学性能。复合材料试样由三种重量百分比的增强材料制备，即3%、6%和9%，基质材料为88%。采用L9正交阵列实验，在载荷、速度和时间等不同参数下，用销盘式摩擦计对试样进行了摩擦学实验。采用扫描电镜和光学显微照片研究了试样磨损表面的磨损机制。研究证实，与其他复合材料相比，用3%碳化硼和9%硅酸锆合成的混合复合材料显示出增强的耐磨性和更低的摩擦系数。

Tribological study on hybrid reinforced aluminium-based metal matrix composites

The demand for aluminium-based metal matrix composites is growing in aerospace and automotive industries because of its good corrosion resistance and high strength to weight ratio. The present work focuses on tribological characteristics of stir cast hybrid composites synthesised with AA6063, Boron carbide and zirconium silicate. Composite specimens were prepared with three percentages of reinforcement materials by weight, i.e., 3%, 6% and 9%, and the matrix material at 88%. Tribological experiments were conducted on the specimens with a pin-on-disc tribometer, using L9 orthogonal array experiments with various parameters including load, speed and time. SEM and optical micrographs were employed to investigate the mode of wear mechanism on worn out surfaces of the specimens. The investigation has confirmed that the hybrid composite synthesised with 3% boron carbide and 9% zirconium silicate has shown an enhanced wear resistance with a lower coefficient of friction as compared to the other composites.
