Abstract

Peroxide cured hydrogenated acrylonitrile/butadiene rubber (HNBR) compounds with 20 parts per hundred rubber (phr) active fillers, such as carbon black (CB), multiwall carbon nanotube (MWCNT) and silica were produced and their friction and wear properties under unlubricated rolling and sliding conditions were evaluated. The network-related properties of the HNBR compounds were deduced from dynamic-mechanical thermal analysis (DMTA). The coefficient of friction (COF) and the specific wear rate (W s) were determined in different home-made test rigs. The CB and MWCNT containing HNBR compounds exhibited the best resistance to rolling and sliding wear, respectively, among the HNBR systems studied. The worn surfaces were inspected in scanning electron microscope (SEM) and the wear mechanisms were analyzed and discussed in respect to the types of wear and fillers.
