Data Sets Formation on the Physical Properties of Oxide Scale Components for Theoretical Assessment of Efficiency Parameters of Laser Cleaning of Carbon Steels and Related Processes

Devoino, O. G.; Gorbunov, A. V.; Lapkovsky, A. S.; Lutsko, N. I.; Shpackevitch, D. A.; Gorbunova, V. A.; Koval, V. A. (БНТУ, 2024)

There is a need in machine-building industries nowadays to automate technologies, in particular, laser ones, to remove surface oxide layers – mill scale, rust – from steel products/pieces in order to improve the energy effectiveness of processing. Herewith, a theoretical assessment method for the intensity of heating of the oxide layer and the phase transition in it can be used ...

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 ...
