Abstract：This study investigated the effects of granulated ZrO2 on the tribological characteristics of lubrication composites. The composite materials were evaluated using constant speed friction and wear tests with the data analyzed using the preference selection index (PSI) method. The results showed that the optimum granulated ZrO2 content in this composite was 10% with the friction factor of 0.49. Fade tests and recovery tests also showed the variations of the wear rate, friction coefficient, fade ratio, recovery ratio, stability coefficient, and the friction fluctuation and variability coefficient for various granulated ZrO2 concentrations.
