选择不同的基体(LD2,ZL101)和不同的颗粒含量(10%,15%,20%),对铝基复合材料的摩擦磨损性能进行了研究,包括滑动速度、压力、表面温度、基体类型、颗粒含量等对复合材料摩擦系数的影响规律,以及制动压力、基体种类、颗粒含量等对复合材料磨损量的影响规律,积累了非连续增强铝基复合材料摩擦磨损方面的数据,证明了非连续增强铝基复合材料具有高的导热性、高的耐磨性.并介绍了国内外铝基复合材料在汽车工业中的应用前景及其应用实例。
The friction and wear properties of aluminum matrix composites were investigated with different substrates (LD2 and ZL101) and different particle contents (10%, 15% and 20%), including sliding speed, pressure, surface temperature, The influence law of particle content and so on on the friction coefficient of the composite material, as well as the influence law of brake pressure, matrix type and particle content on the wear amount of the composite material. The data of the friction and wear of the non-continuously reinforced aluminum matrix composite material have been accumulated. Continuously reinforced aluminum matrix composites have high thermal conductivity and high wear resistance.And the application prospects and application examples of aluminum matrix composites in the automotive industry at home and abroad are introduced.
