The work presents the research results of the influence of the selected technological factors on the improvement of bimetallic castings alloy steel-silumin. The following alloy steel grades were used for the research: X6CrNiTi18-10, X39Cr13 and HS6-5-2. The sets of the mentioned steel grades were alphinated in silumin AlSi5 and were poured with this silumin or complex silumin AlSi5Ni5Cu4MgCrMoWV into the casting mold obtaining bimetallic castings as a result. Moreover, the following technological factors of the process of bimetallic casting production were analyzed: the time from removing of the set from the alphinizing bath till pouring it with the silumin into the casting mold “τ_p”, the temperature of the initial heating of the casting mold “t_2,0” and the temperature of the silumin for pouring of the casting mold “t_z”. It follows from the presented results that the best connecting quality of the analyzed castings is obtained when using: the possible short time “τ_p” and low temperature values “t_2,0” and “t_z”.
