摘要
采用干摩擦磨损试验机研究了速度和载荷对SiC颗粒增强铝基复合材料的摩擦磨损性能的影响,并对比了SiC颗粒增强铝基复合材料与HT250的耐磨性能。结果表明,在试验条件下,随着载荷的增加,磨损率增加,滑动摩擦系数先下降至最低值(载荷为10MPa)后缓慢增加。滑动摩擦速度对滑动摩擦系数和磨损率有着直接影响,随着速度的升高,材料的磨损率增加。在载荷为20MPa,速度为400r/min的高速高载下,材料容易发生严重的粘着磨损。
The effect of speed and load on the friction and wear properties of silicon carbide particle reinforced aluminum matrix composite was studied.And the wear resistance of silicon carbide particle reinforced aluminum matrix composite and HT250 was compared.The results show that with the increase of the load,the wear rate increased and the friction coefficient increased after the first fall.The wear rate was influenced by speed directly,which increased with the increase of the speed.Under the high speed and high load conditions,the material prone to severe adhesive wears.
