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 ...
