摘　　要：利用MRH-3高速环块摩擦试验机考察了Cu、TiO2、Al2O3三种纳米添加剂在液体石蜡中的摩擦学性能,并借助试验后钢件磨损量变化以及磨斑表面SEM图片对比了三种添加剂的摩擦磨损性能。结果表明:纳米Cu添加剂对减少摩擦副表面的磨损以及防止金属面卡咬效果最佳。The tribological behaviors of Cu, TiO2 and Al2O3 nanoparticles as additives in liquid paraffin were investigated with the MRH- 3 high - speed ring - block friction and wear testing machine. Their friction and wear properties were compared and analyzed with the help of the steel wearing and scanning electron microscope （SEM）. The results showed that Cu nanoparticle possesses the best antiwear property as well as preventing metal surface seizure.
