Popis:	The morphology, and mechanical and tribological properties of deproteinized natural rubber with constant viscosity (DPNR) and synthetic cis-1, 4 polyisoprene vulcanizates (IR2200) using ISAF220 carbon black (CB) blends were studied in various ratios: 100/0, 75/25, 50/50, 25/75 and 0/100. Results for different operating test conditions under applied normal load, sliding speed and sliding distance were analyzed. The experimental results showed that the addition of CB (30 phr.) has significantly affected the wear and frictional performance of both DPNR-CV and IR2200 by decreasing the abrasion weight loss by more than 80% compared with the unfilled DPNR and IR2200. Adding 30 phr CB decreases the abrasion weight loss to more than 70%. The surface topography of micro-scales abrasion was characterized by scanning electron microscopy (SEM). Using SEM micrographics, the influence of blend ratios on wear mechanisms and spacing imprinted abrasion patterns was highlighted.
