Development of Cu-SiC composite for electrical discharge machining electrode using powder metallurgy technique
In this research, composites containing 10-50 vol% SiC whiskers reinforced Cu matrix were fabricated using powder metallurgy technique. The mixtures were blended in a ball milling machine with the addition of ethanol for 2 hours at 150 rpm. The mixtures were allowed to dry in an oven at temperatu...

| Summary: | In this research, composites containing 10-50 vol% SiC whiskers reinforced Cu matrix
were fabricated using powder metallurgy technique. The mixtures were blended in a ball milling
machine with the addition of ethanol for 2 hours at 150 rpm. The mixtures were allowed to dry in an
oven at temperature of 40 °C. Then, the mixtures were uniaxially compacted into a cylindrical pallet
of Φ 13.5 x 2 mm under compaction pressure of 472 MPa. It was followed by sintering in vacuum
furnace at temperatures of 800-950 °C for 4 hours. The density, microhardness, electrical resistivity,
thermal conductivity and microscopy analysis of the sintered composites were studied and reported
in this paper. |
