Behavioral Study of Mechanical Properties and Machining of Composite Material Fabricated by Powder Metallurgy

摘要

This research fabricates three different type of composite material with methodology of powder metallurgy. In which base material is copper electrolyte powder and reinforcement materials are tungsten carbide, silicon carbide and graphite. With the help of SEM, EDS and hardness test Microstructure and properties were investigated to know effect of sintering temperature and time (1 hour at 750°C) on fabricated composite materials. The result showed that Cu-SiC composite is having more uniform structure visualized after the sintering, everywhere reinforcement material located in base material. Machining of fabricated composite Cu-SiC is more easy compare than other because it is having more material removal rate (MRR).
