A composite of copper powder reinforced with SiCp (0-10 wt%) in which
aluminum powder of ( 2 wt%) was added for improving wettability of the ceramie
phase. . The composite mixture was prepared by mixing with a ball mill for one
hour to ensure a homogenous distribution on the composite .Gteen compacts
pressed at (350MPa) a steel mold of (12mm)diameter were then sintered at (900
°C) for two hours in an electric furnace, in argon atmosphere . Optical microscopy,
Density, porosity content and Vicker's hardness test were then conducted for the
sintered samples.
Obviously, it was concluded that there was enhancement of the physical and
mechanical (hardness) properties of the sintered compacts with increasing the SiC
content.
Keywords: wettability ,homogenous distribution .load transfer . Interface.
