Abstract EN

The replication casting process gives the open-cell aluminum foams that can be used in many industrial applications as well as in filtering technology.

The essential requirement for filters is the uniformity of filtering degree which is defined by the minimal pore size.

However the structure of replication castings is often inhomogeneous and the minimal pore radius is decreasing in the direction of melt infiltration.

The objective of this investigation is to study the dynamics of melt impregnation of the porous medium by vacuum suction to identify the possibility of reducing the anisotropy.

Theoretical data illustrate the processes at the boundary between melt and gas medium.

The experiments were carried out using the replication aluminum samples produced according to commercial technology.

It was found that the permeability coefficient varies throughout the height of castings.

A method for estimation of pressure on the line of melt movement was proposed.

The resistance of NaCl layer and circular vents of the mold causes the inhomogeneity of castings.

Finally the ways of minimizing the anisotropy were offered.
