In the paper there were presented possibilities of combining metal sheet with metallic foams using a sintering powder mixture in dissociated ammonia. The research were carried out over the properties of sintering powder iron foam, with superalloy HASTELLOY® X, by diffusion joint. The results indicated that there’s a possibility to obtain the satisfying quality joint between the Fe foam and superalloy HASTELLOY® X. The studies were focused on the properties of microstructure and some mechanical characteristics. Example of structural applications for metallic foams, utilizing benefits in weight, stiffness, energy dissipation, mechanical damping, and vibration frequency were summarized already by many authors. That’s why, the author chose to study selected properties of fusion of Fe foam and superalloy sheet metal with new approach. The studies used to determine basic quality parameters of the sintered joint. Using EDS analysis, there were identified a types of alloying elements and the extent of diffusion from superalloy HASTELLOY® X in the course of Fe foam.Keywords: Fe foam, porous material, superalloy
