Morphology of worn surfaces of rubber compounds

The morphology of worn surfaces of three kìnds of rubbers; polybutadiene (BR), styrenebutadiene copolymer (SBR), and natural rubbers (NR), was reported in this paper. A blade abrader was used for the abrasion experiment. The pattern spacing, ridge height, and pattern angle were investigated as a function of frictional work input during the abrasion. The abrasion pattern of BR compound was slightly different from those of SBR and NR. A possible explanation was given for the observed difference. The temperature and lubrication of the abrasion surface greatly affect the abrasion pattern.
