采用销-盘接触方式考察丁腈橡胶／316L 不锈钢配副的摩擦磨损性能，探讨有无 Al2 O3硬质颗粒及颗粒尺寸对其摩擦学行为的影响。通过扫描电子显微镜（SEM）和表面轮廓仪分析配副材料的磨痕表面形貌。结果表明：硬质颗粒参与磨损能降低接触副表面的摩擦因数；大尺寸颗粒会加速橡胶的磨损并能嵌入橡胶基体形成微切削效应，而随着颗粒尺寸减小至数十微米时，颗粒的存在反而能减缓橡胶的磨损；但颗粒的介入均会加剧配副金属的磨损、硬质颗粒的犁削作用使钢球磨损表面存在大量的犁沟；此外，无颗粒及不同尺寸颗粒环境下丁腈橡胶／不锈钢摩擦副表现出不同的损伤机制。

The friction and wear characteristics of acrylonitrile-butadiene rubber/316L stainless steel tribo-pairs were investigated using a sphere-on-disc test device.The influence of Al2 O3 hard particles and the particle size on the tribological behavior of the tribo-pairs was discussed.The morphology of worn surface was analyzed via scanning electron microscope (SEM)and by using a surface profilome-ter.The results show that the particles wear can reduce the friction coefficient of the contact pairs;Large particles can accelerate the wear of rubber and large particles can be embedded into the rubber matrix,resulting in micro cutting effect,however,as particle size decreases to about dozens of mi-crons,the existence of particles can mitigate the wear of rubber;All the particles embedded in the rubber matrix can aggravate the wear of metal counterpart and lots of furrows can be observed on met-al worn surface caused by the ploughing effect of hard particles;In addition,the NBR/stainless steel tribo-pairs exhibit different damage mechanism under conditions of no particles and particles with dif-ferent size.
