Abstract

Disclosed are materials of variable density or tiered porosity micro-fluidic porous media structures of sintered metal or other materials, and methods of making same. An embodiment discloses an aluminum porous media element of variable density having a tiered porosity micro-fluidic media structure. A method of making the aluminum porous media element disclosed herein includes mixing a binding agent with a metal powder to generate a first mixture, heating the first mixture to a sub metal sintering temperature to get a homogeneous composite of the metal powder and heating the homogeneous composite to a metal sintering temperature to sinter-bond the metal powder to get a porous media of first porosity.
