Use of water-soluble precursors in the production of cast metal foams

Abstract

The paper is devoted to the field of manufacturing cast metallic foams - porous metal materials - with a stochastic arrangement of the inner cavities. The mastering of inexpensive ways of manufacturing metallic foams is a prerequisite for a full utilization of such a material. That is why the experimental part was devoted to the casting technologies for the production of metal foams based on conventional foundry processes. In the experiment, the infiltration of molten metal into mould cavities filled with precursors was tested. Particular attention was paid to the use of water-soluble precursor materials. It is assumed that a thorough knowledge of the production parameters and conditions will contribute to the expansion of the foundry range, which can also increase the competitiveness of this industry on a global scale.
