Conclusions

  1. 1.

    In the zone of fusion of steel-silicon or aluminum bronze bimetals produced by welding, facing or casting the diffusional interlayers have a columnar structure and the grain boundaries of the interalayer are perpendicular to the surface of separation and rich in diffusing copper and silicon or aluminum.

  2. 2.

    The interlayer in the fusion zone of the bronzes investigated with steel St3 consists of alloyed ferrite with lattice constants of 2.854–2.877 Å and 2.878–2.880 Å for bimetals Br. KMts3-1-St3 and Br. AMts9-2-St3, respectively.

  3. 3.

    To reduce the thickness of the interlayer it is necessary that the temperature and time of the interaction of bronze with steel be minimal. Thus, it is preferable to surface steel with bronze by condensation of the bronze without melting the steel, with minimal heating of the bronze.
