Abstract

The subject of the study is to study the structures of aluminum foam and copper foam by electron microscopy with the introduction of a pore-forming agent in the form of CaCO3 bird egg shell powder. Purpose of the study: analysis of the structure of the resulting sintered material, homogeneity of the pore structure, obtaining an image of the surface morphology and determining the size of the pores formed during the decomposition of the pore-forming element in the matrix of the presented metal microstructures. When studying the fine structure of foam-metal samples by electron microscopy, a multi-purpose scanning (raster) microscope JSM-6380LV (Japan) was used. The object of the study is the obtained sintered samples of aluminum foam and copper foam. The main results of the study: a study of the influence of porosity on the quality of the material, the fine structure of the obtained foam metal samples and an electron microscopy study of the morphology of the pore space, which affects the mechanical characteristics of materials
