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。
In order to compare the tribological properties of two kinds of boron carbide particles reinforced aluminum matrix composites, the samples were machined into pin samples and compared with the steel disk samples respectively on the multi-purpose friction and wear testing machine for friction and wear tests. Effect of contact load and relative sliding velocity on friction and wear properties of two composites. The results show that the wear amount of boron carbide reinforced aluminum matrix composites increases with the increase of load and relative sliding velocity, while the friction coefficient decreases with the increase of load and relative sliding velocity. The higher boron carbide composites The wear resistance is better than the low content of the composite material.
