【Abstract】 By using self-made dry sliding testing apparatus, the investigations were made on the tribological characteristics of three composites and comparative materials against semi-metallic friction material. The experimental results indicate that with increasing of contact pressure the rate of wear of materials increases and with increasing of sliding speed the rate decreases. The rate of wear of ZL101 alloy is higher than composites about three degrees. The rate of wear of composites is of one third of HT250. With increasing of contact pressure and sliding speed, the frictional coefficient decreases for all of the materials. The frictional coefficient of composites corresponds to that of HT250 and the composites excels HT250 in the stability of frictional coefficient.更多还原
