Abstract

The ability to achieve close control of porosity and pore size is the main reason that
filters are produced by powder metallurgy. This study was performed using bronze alloy
powder (Cu-7.5%Sn- 0.1%Fe-0.3%Pb-0.15%Zn). The samples were prepared by two
methods :(1) cold die compacting at different particle size, compacting pressure, sintering
time, and sintering temperature, and (2) loose powder sintering. The compacts were sintered
under controlled atmosphere. After surface preparation of the samples, the microstructure was
used to compute the apparent porosity. It was found that the(Loose Powder Sintering) method
is optimum method to produce highly porous materials with (~59%) porosity when selecting
the proper conditions. The porosities obtained using cold die compaction are ranging between
(5-41%) and sintered density ranging between (58.6-94.3%) of the theoretical mean density of
the starting materials
