The paper presents conception and production method of skeleton composite castings with use of cast steel G35CrSiMnMoNi skeleton casting and chromium cast iron EN-GJN-XCr15 filling. Working elements in winning machines and devices, which work in intensive aberasive wear i.e. liner of exhausters, percussive and ram hammers, are destination of bimetallic castings. Skeleton geometry was based on three-dimensional symmetrical cubic net consisting of circular connectors and nodes joining 6 connectors according to Cartesian coordinate system. Dimension of an elementary cell was equal to 10 mm and diameter of single connector was equal to 5 mm. In range of studies were casted cast steel skeletons with chromium cast iron filling and based on metallographic research on light and scanning electron microscope was made quality assessment of joint in bimetallic castings. Moreover in range of studies was used microanalysis of chemical composition in transition zone of cast steel-cast iron joint.
