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 “τp”, the temperature of the initial heating of the casting mold “t2,0” and the temperature of the silumin for pouring of the casting mold “tz”. It follows from the presented results that the best connecting quality of the analyzed castings is obtained when using: the possible short time “τp” and low temperature values “t2,0” and “tz”.
