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 ...
