| Description
| - Porous metals and metallic foams are metallic materials containing pores in their structure that are intentionally created. Their specific structure then gives them a very advantageous combination of physical and mechanical properties, such as low density and high rigidity along with high capability of absorption of impact energy. Since the discovery of porous metallic materials numerous methods of production have been developed. Some technologies are similar to those for polymer foaming, others are developed with regard to the characteristic properties of metallic materials, such as their ability to sintering or the fact that they can be deposited electrolytically. According to the state, in which the metal is processed, the manufacturing processes can be divided into four groups. Porous metallic materials can be made from liquid metal, from powdered metal, metal vapours, or from metal ions. Porosity may achieve from 30% to 93%, depending on the method of production and material used. The aim of the experiment was to verify the possibilities of production of metallic foams by conventional foundry processes and to study the process conditions. The work is focused on the production of cast metallic foams with open structure by use of various types of filler material. Mastering of production of metallic foams with defined structure and properties using gravity casting into sand or metallic foundry moulds will contribute to an expansion of the assortment produced in foundries by completely new type of material, which has unique service properties thanks to its structure, and which fulfils the current demanding ecological requirements. In Czech Republic cast metallic foams are not yet produced.
