The paper presents the technology of bimetallic castings using the casting method of applying layers directly during the casting process. The bimetallic casting consists of a load-bearing part (typical casting material, i.e. gray cast iron with flake graphite) and a working part (titanium insert). The titanium insert was made by printing using the selective laser melting (SLM) method, and its shape was spatial. The verification of the bimetallic castings was carried out mainly based on metallographic tests, temperature and thickness measurements. Structure examinations containing metallographic microscopic studies with the use of a light microscope (LOM) and a scanning electron microscope (SEM) with microanalysis of the chemical composition (energy dispersive spectroscopy - EDS).The aim of the tests was to select the appropriate geometrical insert parameters for bimetallic castings within the tested range. The correct parameters of both the insert, pouring temperature and the casting modulus affect the diffusion processes and, consequently, the formation of carbides and the creation of bimetallic castings.
