3Al_2O_32SiO_2（f）／ZL109复合材料的润滑摩擦磨损特性

Characteristic of Friction and Wear for 3Al 2O 3·2SiO 2(f) /ZL109 Composites under the Lubricated Conditions

研究了挤压铸造纤维增强复合材料３Ａｌ２Ｏ３２ＳｉＯ２（ｆ）／ＺＬ１０９的油润滑滑动摩擦磨损特性。结果表明：与ＺＬ１０９相比，复合材料的滑动摩擦系数减小，耐磨性显著提高。通过对磨面形貌的扫描电镜观察，分析了复合材料和ＺＬ１０９合金的磨损机制。

The characteristic of friction and wear for fibre reinforced composite of 3Al 2O 3·2SiO 2(f) /ZL109 produced by squeeze casting under the lubricated sliding friction conditions has been investigated.The results revealed that the reinforcement using 3Al 2O 3·2SiO 2 fibre can significantly increase wear resistance of ZL109 alloys and reduce the sliding friction coefficient.The wear mechanisms of both the composite and the ZL109 alloy were analyzed using SEM.
