Abstract

In this research work, copper-based friction materials have been developed by using press and sinter method. Pre-alloyed bronze (Cu-10Sn) powder was admixed with iron (Fe), graphite (C) and varied amounts of silicon carbide (SiC) powders. The admixed powders were compacted into disc-shape samples, which were then sintered at different temperatures in the range of 800-950 ฐC. The sintered Cu based friction materials showed decreases of sintered density, hardness and wear resistance with increasing temperature and SiC content. Both sintering temperature and SiC caused local melting where the pore was generated when the melt penetrate to somewhere else. Although with high porosity, sintered Cu based friction materials with high SiC contents showed high friction coefficient. ฉ (2015).
