硅酸铝纤维增强铝硅合金复合材料的减摩性

Antifriction Property of Aluminosilicate Short Fiber Reinforced\= Aluminium\|Silicon Alloy Composite

利用ＭＬＤ－１０磨损试验机，探讨热处理条件、磨损环境等对ＺＬ１０９合金、复合材料与硼蠕铁组成摩擦副的磨损特征。试验结果表明：在有润滑条件下，经Ｔ６处理的复合材料比ＺＬ１０９合金有更为优异的耐磨性。过时效处理的复合材料比Ｔ６处理的复合材料更耐磨，而作为他们的对摩材的硼蠕铁的磨损量比与ＺＬ１０９合金组成摩擦副的硼蠕铁的磨损量要低得多。在没有润滑条件下，复合材料的耐磨性也远比ＺＬ１０９合金的好。

The wear characteristcs of both ZL109 alloy/boron alloyed compacted graphite iron and composite/boron alloyed compacted graphite iron rubbing pairs were investigated under different environmental and heat\|treated conditions by using MLD\|10Wear testing machine. The results show that, under the condition of oil lubrication, the composite after T\-6 treatment exhibits excellent wear resistance compared with the ZL109 alloy. The composite fafter over\|aged treatment enjoys better wear resistance than the composite after T\-6 treatment. While the wear mass loss of boron compacted graphite iron in friction pair with the composite is much lower than that with ZL109 alloy, under dry condition, the same results were achieved.\=
