Powder Metallurgy Route

Porous Copper (porous Cu) with varying porosities was prepared using sodium chloride (NaCl) particles as space holder through powder metallurgy route. Pre-alloyed copper that was used as a feedstock material were mixed with the varying proportion (0%, 20%, 40% and 60% of volume fraction) of laboratory grade NaCl prior to hot compaction. The green compacts were subjected to water leaching process in order to remove NaCl particles and consequently being sintered at 850°C. The resultant porous Cu were examined in terms of density, porosities, microstructures and dimensional changes. The effect of space holder on the occurrence of pores in sintered article was investigated. It was found that the amount and shape of the space holder particle greatly affect the percentage of porosities and the shape of the pore of the sintered article.
