Research of surface treatment of mechanical engineering products (materials) with an electron beam

The article presents a review of recent publications on research on the use of an electron beam for surface treatment of machine-building products. Electron-beam technologies allow processing of surfaces of parts of various complexity made of different alloys. The article shows that over the past 7 full years in Russia, 27 theses have been defended on the subject under consideration. The content analysis of scientific publications has shown that the methods of electron beam processing can be classified according to three characteristics: 1) by the type of atmosphere created; 2) on the use of the additive material; 3) on the presence of accompanying methods of influence on the material.
