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 ...

On Energy Efficiency Characteristics of Laser Erosion on Oxidic Surfaces of Carbon Steels, Cast Iron and Low-alloy Non-ferrous Alloys During Deoxidizing Cleaning. Part 1

Devoino, O. G.; Gorbunov, A. V.; Shpackevitch, D. A.; Lapkovsky, A. S.; Gorbunova, V. A.; Koval, V. A.; Kovaleva, S. A. (БНТУ, 2025)

A comparison of operating characteristics has been carried out for laser erosion cleaning (LC) processes studied in recent years and prospective for metalworking manufacturing of products/pieces from a number of carbon steels, cast iron and low-alloy non-ferrous metal alloys from oxidized layers formed as products of gas or other corrosion, often having inhomogeneous structure ...

On Energy Efficiency Characteristics of Laser Erosion on Oxidic Surfaces of Carbon Steels, Cast Iron and Low-alloy Non-ferrous Alloys During Deoxidizing Cleaning. Part II

Devoino, O. G; Gorbunov, A. V.; Shpackevitch, D. A.; Lapkovsky, A. S.; Gorbunova, V. A.; Koval, V. A.; Kovaleva, S. A. (БНТУ, 2025)

An analysis of the energy efficiency characteristics was performed for laser erosion cleaning (LC) processes developed last period for the application in metalworking sector for the wide group of carbon steels, cast iron and non-ferrous metal alloys to remove surface oxidic layers. The consideration of some characteristics of the LC-processes (energy consumption, energy criterion ...
