中文摘要：
为了比较两种含量不同的碳化硼颗粒增强铝基复合材料的摩擦学性能，将其加工成销试样，在多功能摩擦磨损试验机上分别与钢盘试样进行对比摩擦磨损试验，重点研究了接触载荷和相对滑动速度对两种复合材料摩擦磨损性能的影响。结果表明：碳化硼增强铝基复合材料的磨损量随载荷与相对滑动速度的增大而增大，而摩擦因数随载荷与相对滑动速度的增大而减小，较高碳化硼含量的复合材料的耐磨性能比较低含量的复合材料好。
英文摘要：
In order to compare the tribologieal properties of two aluminum matrix composites reinforced by different content of P~C particles, the pin samples were prepared with them and friction and wear tests of pitt-on- steel disc were carried out on a multifunctional tribometer. The influences of contact load and sliding velocity on friction and wear performance of two composites were expressly investigated. The result show that the wear mass loss of the aluminum matrix composites reinforced by B4C particulates increased with the increase of contact load and sliding velocity. The friction coefficient of the composite pin vs steel disc decreased with decreasing contact load and sliding velocity. The wear resistance of higher content of B4C particulate composite was better than that of lower content of B4C particulate composite.
