| 摘 要： | 提出了三维陶瓷网络（骨架）增强金属基复合材料的新构思，设计和制备了一种新型的三维陶瓷网络（骨架）增强铝合金复合材料，研究了其在干摩擦状态下的滑动摩擦磨损行为。结果表明，基体铝合金在重载时产生严重粘着磨损，磨损层发生软化和塑性流动，而复合材料中的陶瓷颗粒暴露于磨损表面并起承载作用，从而保护基体不发生严重磨损，复合材料对磨环的磨损量大于基体合金对磨环的磨损量，但复合材料摩擦副的总摩损量比基体合金摩擦副的小。

| Abstract: | A new idea of metallic composites reinforcoed with three dimensional network ceramics(skeleton)is put forward. The aluminum alloy composites reinforced with three dimensional network ceramics(skeleton) is designed and fabricated. The sliding friction and wear properties of the composites are studied. Experimental results show that heavy load result in serious adhesive wear, micro-hardness decrease and sub-surface plastic deformation for the unreinforeed aluminum alloy. For the composites,the ceramics particles exposed on the sliding surface of the composites support the load, thus preventing the matrix from severe wear, and the wear rate of the composite against grinding ring is more than that of matrix, but the total wear rate of composite-GCr15 system is less than that of matrix-GCr15 system. |
