Abstract

Open porous metals can be made by direct hot isostatic press (HIP) treatment on a cold isostatic pressed body. In this work, porous metals with uniaxially penetrating pores were produced using a modified HIP method.

Penetrating pores from one surface to the other surface are useful for filter applications, and were produced by forcing pressurized gas to travel through samples by alternating the HiPping pressure during sintering.

In this experiment, copper powder was used. Samples produced with this new method have higher permeability coefficient than those produced by the normal HIP method.
