    • On the bonding strength of Fe-based self-fluxing alloy coating deposited by different methods on the steel substrate 

      Feldshtein, E.; Kardapolava, M. A.; Dyachenko, O. V. (University of Zielona Góra, 2018)
      In the present paper, the bonding strength of Fe-based self-fluxing alloy coating deposited by plasma spraying, gluing and laser remelting and alloying on the steel substrate have been investigated. When flame melting, a globular structure is formed. Against the background of the solid solution carbide-boride phases are clearly distinguishable, between which the Fe-Fe2B and Fe-FeB ...

    • Structure-phase condition and tribological properties of coatings based on self-fluxing nickel alloy PG-12N-01 after laser surfacing 

      Devoino, O. G.; Kardapolava, M. A.; Lutsko, N. I.; Feldshtein, E. E. (Kluwer Academic/Plenum Publishers, 2017)
      Some parameters of laser surfacing of self-fluxing nickel alloy PG-12N-01 are considered. Different structures containing a low-melting -Ni – Ni3B eutectic and a -Ni – Cr3C2 eutectic that crystallizes at a higher temperature and forms the strength skeleton of the coating may form depending on the rate of the surfacing. The effect of the rate of the surfacing on the wear resistance ...
