Abstract
Abstract In this study, the size effect of zircon (ZrSiO4) on the tribological characteristics of polymer matrix friction composites were investigated. Hence, four friction composites containing micro and nano-sized zircon particles (5 and 10 wt%) were developed and produced using powder metallurgy method. Their wear and friction characteristics were examined using a friction-wear test device. The weight loss and specific wear rate were measured and compared with that obtained for microsized zircon particles. The surfaces of samples were analyzed using a scanning electron microscope, and less wear was observed in the samples containing nano-sized zircon particles. The results revealed that the size of abrasive particles plays a key role in enhancing the friction coefficient and friction stability.
