Application of a Low-Energy High-Current Electron Beam for Modification of the Surface of Steel Alloyed by the Electro-Explosive Method

Modification of carbon steel surface edges using electro-explosive alloying (EEA) and subsequent treatment with a pulsed electron beam is discussed. The research shows that the combined use of these technologies leads to significant improvements in the material’s performance characteristics, such as microhardness and wear resistance. During the experiments, the optimal electron beam energy density and number of pulses have been determined, making it possible to achieve maximum microhardness values exceeding those of the uncoated steel. Changes in the surface structure, including the formation of microcracks and dendritic crystallization, are also analyzed. The results show that the proper selection of processing parameters improves the physicochemical properties of the steel, making this technology promising for use in various industries.
