Sažetak
Aluminium foams are materials with a cellular structure that can be achieved in several ways. The most common methods are direct foaming of melt and foaming a compacted Al precursor containing a foaming agent. As a foaming agent, titanium hydride (TiH2) has the most widespread application and among some other disadvantages has a high price which significantly increases the cost of foam production. In order to reduce the costs, carbonates, such as calcium carbonate (CaCO3) are successfully used as foaming agents. This paper presents the advantages and disadvantages of using TiH2 and CaCO3 and the recent results of research conducted so far. The decomposition of CaCO3 begins at higher temperatures than TiH2, which gives a finer foam structure. At the end of the paper, the properties of reinforced metal foams are presented, in which the reinforcement with ceramic particles leads to the improvement of compressive properties with the inevitable reduction of the ductility of the foam itself.
