This paper is devoted to the study of processes for the development of high-quality foamed metals based on aluminum and copper matrices by optimizing the parameters of a powder foaming agent. The relevance of the study is due to the need to achieve a uniform cellular structure and specified physico-mechanical properties of metallic foams, which directly depends on the chemical purity and concentration of the gas-forming agent. In the course of the work, a comprehensive chemical analysis of the composition of the used foaming agents (calcium carbonates) is carried out using a high-precision wave-dispersive X-ray fluorescence spectrometer Rigaku ZSX. This method makes it possible to identify the presence of trace elements and oxide phases that affect the dynamics of thermal decomposition of the substance. The problem of selecting the optimal quantitative content of a foaming agent in the metal charge in order to achieve the required level of porosity and structural uniformity is solved experimentally. The study results bring to finding correlations between the elemental composition of the foaming agent, its mass fraction in the matrix, and the final qualitative characteristics of the obtained foam metal samples. The data obtained will make it possible to optimize the technological regulations for the development of porous materials with open and closed cells for the needs of the aircraft industry, energy industry and transport machinery industry.
