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 Al2O3 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 profilometer. 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 microns, 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 metal 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 different size.
